Freight operations in South Africa face scrutiny at every weigh station, roadblock, and traffic checkpoint on our national routes. Yet load securing remains one of the most misunderstood compliance areas for transport operators. The National Road Traffic Act (NRTA) and its regulations set out specific requirements for how goods must be secured on vehicles, but many operators only discover the details when facing a fine or, worse, after a load shift causes an accident.
This guide breaks down exactly what the NRTA requires for load securing, the forces your securing equipment must withstand, and the common failures that traffic officers look for during inspections. Whether you haul general freight on the N3 between Durban and Gauteng or move bulk commodities across provincial boundaries, understanding these requirements protects your operating licence, your drivers, and other road users.
What Does the NRTA Actually Require for Load Securing?
The National Road Traffic Regulations, published under the NRTA (Act 93 of 1996), establish clear obligations for load securing. Regulation 247 states that goods must be secured in a manner that prevents them from falling, hanging, or dragging from the vehicle. But this broad requirement is backed by specific technical standards.
The key requirements include:
- Goods must not shift or fall during normal driving conditions, including emergency braking, acceleration, and cornering
- Securing equipment must be appropriate for the type, weight, and nature of the goods
- Visual inspection must be possible - traffic officers must be able to verify securing without unloading
- Excess goods must not project beyond prescribed limits without proper permits
The regulations reference SANS standards for load restraint, particularly SANS 10263, which provides detailed guidance on securing methods and equipment specifications. While SANS 10263 is not legally mandated in all circumstances, it represents the technical standard against which load securing is often assessed.
What Forces Must Your Load Securing Withstand?
Here is where many SA freight operators get caught out. Load securing is not just about preventing goods from bouncing off the vehicle. It must resist specific forces generated during transport.
According to SANS 10263 and international best practice applied in SA:
- Forward force (braking): The load must withstand a force equal to 0.8 times the load weight pushing forward
- Rearward force (acceleration): 0.5 times the load weight pushing backward
- Sideways force (cornering): 0.5 times the load weight pushing to either side
- Upward force (road surface): 0.2 times the load weight lifting upward
For a 10-tonne load, this means your securing must resist:
- 8 tonnes forward
- 5 tonnes rearward
- 5 tonnes sideways
- 2 tonnes upward
These forces can act simultaneously. A truck braking while cornering experiences combined forces that your securing system must handle. This is why traffic officers look closely at how loads are secured, not just whether something is holding them in place.
Take Action
Calculate the actual forces your typical loads generate and verify that your securing equipment's Working Load Limit (WLL) meets or exceeds these requirements. Document these calculations as part of your freight management system.
Types of Load Securing Methods Under SA Law
The NRTA does not prescribe a single securing method. Instead, it recognises that different loads require different approaches. The three primary methods are:
Blocking and Bracing
This method uses physical barriers to prevent load movement. The load is placed against fixed structures (headboards, side walls) or restrained by purpose-built blocking materials.
Requirements:
- Blocking material must be strong enough to resist calculated forces
- Bracing must be secured to the vehicle structure
- Gaps between load and blocking must be filled to prevent shifting
Blocking is often the primary securing method for heavy, dense loads where friction alone provides significant restraint.
Lashing (Tie-Down)
Lashing uses straps, chains, or ropes to press the load against the vehicle deck. The friction generated between load and deck surface provides the restraining force.
The critical calculation: For tie-down lashing to work, you need enough downward force to generate sufficient friction. The formula is:
Lashing force required = (Restraint force needed) ÷ (Friction coefficient × Number of lashings)
A load on a timber deck (friction coefficient approximately 0.45) needs more lashings than the same load on a rubber mat deck (friction coefficient approximately 0.6).
Direct Restraint
This method attaches securing equipment directly to the load via lashing points, hooks, or purpose-built attachments. The securing equipment directly resists the movement forces rather than relying on friction.
Direct restraint is required when:
- The load has designated lashing points
- Friction-based securing cannot achieve required forces
- The load shape makes blocking impractical
Many SA operators use a combination of methods. For example, blocking at the front combined with tie-down lashing to prevent rearward and upward movement.
Chain and Strap Working Load Limits for SA Freight
Your securing equipment must have a Working Load Limit (WLL) sufficient for the forces involved. This is where non-compliance often occurs.
Chain Specifications
Chains used for load securing must meet specific grade requirements:
| Chain Grade | Approximate WLL per mm² | Common Use |
|-------------|-------------------------|------------|
| Grade 70 | Higher strength | Transport chains |
| Grade 80 | Highest for general transport | Heavy loads |
| Grade 43 | Standard proof coil | Light securing only |
Critical requirement: Chains must be marked with their grade and WLL. Unmarked chains cannot be verified and may be rejected during inspection.
Strap Specifications
Webbing straps (ratchet straps) are the most common securing method for general freight:
- 50mm straps: Typical WLL of 2,000 to 2,500kg per strap
- 75mm straps: Typical WLL of 4,000 to 5,000kg per strap
- 100mm straps: Typical WLL of 6,000 to 8,000kg per strap
The strap must be labelled with its WLL. Unlabelled straps are a common cause of roadblock failures.
Lashing Capacity Calculation
For tie-down lashing (pressing load against deck), the Lashing Capacity (LC) needed is:
Total LC required = Sideways force ÷ (Friction coefficient × 2)
The "× 2" accounts for the strap passing over the load and securing on both sides.
For a 5-tonne load on a timber deck requiring 2.5 tonnes sideways restraint:
- LC required = 2,500kg ÷ (0.45 × 2) = 2,778kg
This means at least two 50mm straps (at 2,000kg WLL each provides 4,000kg total capacity) would be the minimum.
Pre-Trip Inspection Requirements for Load Securing
The NRTA requires drivers to ensure loads are properly secured before departure and to check securing during the journey. This is not optional guidance - it is a legal obligation.
What Drivers Must Check
Before departure:
- All securing equipment is correctly applied and tensioned
- No visible damage to straps, chains, or tensioners
- Load has not shifted from its intended position
- Securing equipment WLL is appropriate for the load
During the journey:
- Check securing after the first 50km of travel
- Re-check at every stop or when loads are added/removed
- Immediate action if any loosening or shifting is detected
T-ERP's driver performance management module can integrate pre-trip checklists that include load securing verification, creating a documented record of compliance.
Take Action
Implement a mandatory pre-trip checklist that includes specific load securing items. Require drivers to digitally confirm checks, and include photographic evidence for high-value or sensitive loads.
Common Load Securing Failures Found at SA Roadblocks
Traffic officers at weighbridges and roadblocks across South Africa see the same securing failures repeatedly. Understanding these patterns helps you avoid them.
Insufficient Securing for Load Weight
The most common failure. Operators use one or two straps regardless of load weight. A 10-tonne load restrained by two 50mm straps simply does not meet the force requirements.
The fix: Calculate forces, determine required lashing capacity, and use enough securing equipment.
Damaged or Worn Equipment
Straps with cuts, fraying, or damaged stitching are rejected. Chains with stretched or deformed links fail inspection.
What officers look for:
- Cuts or abrasions on straps exceeding 10% of width
- Missing or illegible WLL labels
- Kinked or twisted chains
- Bent or cracked hooks and tensioners
Incorrect Tensioning
Loose straps provide no restraint. Over-tensioned straps may damage the load or the strap itself. The correct tension depends on the securing method and load type.
Poor Load Distribution
A load secured properly but positioned incorrectly can still fail compliance. Officers check that:
- Load is centred on the vehicle
- Weight distribution meets axle requirements (refer to our overloading management guide)
- Height does not exceed 4.3m from road surface
Unsecured Loose Items
Dunnage, tarpaulins, ropes, and spare securing equipment must also be secured. Loose items on a vehicle are a separate offence.
How to Document Load Securing for Compliance
Documentation protects you when disputes arise and demonstrates a systematic approach to compliance. This is particularly important for RTMS-accredited operators who must show ongoing compliance.
Records to Maintain
- Load securing calculations for standard load types
- Equipment inspection records showing regular checks
- Training records for drivers and loading personnel
- Photographic evidence of securing for high-value or complex loads
- Incident reports for any securing failures or near-misses
T-ERP's Operations & Freight module can store standard securing requirements per load type, automatically generating checklists and maintaining digital records that are audit-ready.
Training Requirements
While not explicitly mandated by the NRTA, training is implied by the duty to secure loads properly. The Road Traffic Management Corporation recommends that all personnel involved in loading and securing receive appropriate training.
Training should cover:
- Force calculations and WLL requirements
- Correct application of securing equipment
- Pre-trip and en-route inspection procedures
- Legal obligations and consequences of non-compliance
The Consequences of Load Securing Failures in SA
Non-compliance carries serious consequences beyond fines:
Financial Penalties
Fines for load securing failures vary by province and specific offence, but can range from R1,500 to R15,000 per offence. Multiple failures on a single vehicle compound quickly.
Operational Delays
A vehicle detained for securing failures cannot complete its delivery. Delay costs, including driver wages, missed delivery windows, and customer penalties, often exceed the fine itself. Our guide on freight operational challenges details the full cost impact.
Licence Implications
Repeated load securing failures contribute to operator non-compliance records. This affects operator licence renewals and can trigger operating permit reviews.
Liability for Incidents
If a load securing failure causes an accident, the operator faces potential criminal charges, civil liability, and insurance claim rejection. This extends to directors under certain circumstances.
Practical Steps to Improve Load Securing Compliance
Moving from understanding to action requires systematic change. Here is how SA freight operators can improve:
1. Standardise Securing Methods by Load Type
Create standard operating procedures for each load type you carry. Document the required securing method, equipment quantities, and force calculations. Store these in your freight management system for easy reference.
2. Invest in Proper Equipment
Cheap securing equipment fails inspection and fails in use. Invest in:
- Straps and chains with clear WLL markings
- Ratchet tensioners that function correctly
- Corner protectors to prevent strap damage
- Load bars and blocking materials as needed
3. Train Your People
Drivers and loading personnel need practical training, not just a handbook. Include:
- Hands-on securing demonstrations
- Force calculation exercises
- Inspection identification of worn equipment
4. Inspect and Replace Equipment
Implement a scheduled inspection regime for all securing equipment. Replace equipment before it becomes non-compliant.
5. Use Technology to Track Compliance
Digital checklists, photographic evidence, and systematic record-keeping demonstrate due diligence. T-ERP integrates these functions into your daily operations, creating an auditable compliance trail.
How T-ERP Supports Load Securing Compliance
Managing load securing compliance across a fleet requires more than good intentions. T-ERP's Operations module provides:
- Digital pre-trip checklists that include load securing verification
- Load type profiles with standard securing requirements
- Driver training records tracked and accessible for audit
- Incident reporting with root cause analysis
- Equipment tracking for securing equipment inspection and replacement scheduling
When combined with real-time operational visibility, T-ERP helps you identify securing compliance issues before they become roadblock failures.
Conclusion
Load securing is not a grey area in SA freight operations. The NRTA sets clear requirements, SANS standards provide technical guidance, and traffic officers actively enforce compliance. Yet many operators continue to treat securing as an afterthought rather than a core operational requirement.
The key takeaways for SA freight operators are straightforward:
- Know the forces your loads generate - forward, rearward, sideways, and upward
- Match securing equipment WLL to calculated force requirements, not guesswork
- Inspect and document securing before departure and during travel
- Train personnel on correct methods and legal obligations
Implementing systematic load securing compliance protects your operating licence, your drivers, and your bottom line. The cost of proper equipment and training is insignificant compared to fines, delays, and liability exposure.
If you are still managing load securing with manual checks and paper records, it is time to consider how an integrated freight management system can systematise compliance. See how T-ERP handles load management and compliance documentation - book a demo.

Frequently Asked Questions
What is the minimum number of straps required to secure a load in South Africa?
There is no fixed minimum number specified in the NRTA. The requirement is that securing must prevent load movement under calculated forces. This means a light load may need fewer straps than a heavy one, but the combined Working Load Limit must match the forces involved. Always calculate based on load weight rather than applying a fixed number.
Can I use ropes instead of straps for load securing?
Ropes are legally permitted but must have sufficient strength for the load. However, rope strength degrades with use and is difficult to verify. Most commercial operators prefer rated webbing straps because they carry clear WLL markings and are easier to inspect. Traffic officers may scrutinise rope securing more closely.
How often must I replace load securing straps?
The NRTA does not specify replacement intervals. Straps must be replaced when they show damage affecting more than 10% of their width, when stitching is damaged, or when WLL labels are no longer legible. Many operators implement annual replacement for frequently used straps as a precaution.
Does RTMS certification have additional load securing requirements?
Yes, RTMS-accredited operators must demonstrate systematic load securing procedures as part of their accreditation. This includes documented procedures, training records, and evidence of ongoing compliance monitoring. RTMS audits specifically assess load securing practices against the scheme's requirements.
Who is responsible for load securing - the driver or the operator?
Both carry responsibility. The driver must ensure the load is secured before moving and check during the journey. The operator must provide adequate securing equipment, training, and systems. In practice, a load securing failure often results in penalties for the driver at the roadblock, but operator liability applies in subsequent regulatory proceedings or accident investigations.
