Special Motor Vehicle Permit (Abnormal Loads)

Who needs this permit

Transport operators, plant hire companies, construction firms and manufacturers moving oversized or overweight loads.

When is it required

Before the trip. Travelling with an abnormal load without a permit is an offence and invalidates most insurance cover.

Eligibility

• The vehicle and load can be moved safely with the proposed configuration
• The route can carry the axle loads, including all bridges
• Escort vehicles and, where required, traffic escorts can be arranged

Documents you need before applying

• Completed abnormal load permit application for each province on the route
• Full vehicle and load dimensions, axle configuration and masses
• Proposed route with bridges and structures identified
• Vehicle registration and roadworthy details
• Insurance details
• Escort vehicle arrangements meeting the regulation standards

How to apply — step by step

1. 1

   Measure and weigh accurately

   Permits are issued against exact dimensions and axle masses. A load that differs from the permit is unpermitted.

2. 2

   Plan the route with structures in mind

   Bridges, overhead cables, level crossings and low structures determine the route. Provincial engineers assess bridge capacity.

3. 3

   Apply to each roads authority on the route

   Provinces issue their own permits; SANRAL is involved for national routes and municipalities for local roads.

4. 4

   Arrange escorts and travel-time restrictions

   Larger loads need escort vehicles, and travel is often restricted to specific hours, or prohibited at night, weekends or on public holidays.

5. 5

   Carry the permit and follow the route exactly

   Deviating from the permitted route or times voids the permit.

Where, how much, how long

Common mistakes to avoid

• Applying in only one province for a cross-province route
• Understating axle mass, which is picked up at weighbridges
• Travelling outside the permitted hours
• Using escort vehicles that don't meet the equipment standards

Tips to speed up your application

• Recce the route physically before the trip, especially overhead clearances
• Keep a copy of each provincial permit in the cab
• Build weighbridge stops into the schedule to prove compliance
