Large trucks, buses and vehicle combinations carry more mass and occupy more road space than ordinary cars. This means drivers must plan further ahead for braking, turning, lane changes and parking. Their size also means other road users should avoid cutting in closely or assuming they can turn as tightly as a passenger car. Heavy-vehicle driving requires the appropriate licence category. South African licensing information distinguishes light motor vehicles from heavier categories such as C1, C, EC1 and EC. The correct category depends on the vehicle’s mass and whether it is a combination vehicle. When sharing the road with large vehicles, leave extra following distance, avoid blind spots and expect wide turns. Do not overtake a truck and immediately pull in front of it. Give its driver enough room to see you and enough stopping space to respond safely.

Frequently Asked Questions
Why do trucks need more stopping distance?
Their greater mass and size mean they generally need more space and planning to slow or stop safely.
Why do trucks make wide turns?
Their length and turning geometry require more road space than a normal car, especially when towing.
Should I drive closely in front of a truck?
No. Leave enough space so the truck driver can see you and has room to brake safely.
Do heavy vehicles require different licence categories?
Yes. South Africa uses separate licence categories for different vehicle masses and combinations.
