Large vehicles have significant blind spots around the front, sides and rear. A truck driver may not be able to see a small car, motorcycle or cyclist travelling close beside the cab or directly behind the trailer. This is why drivers should avoid lingering alongside heavy vehicles, particularly on the left side or near the rear. If you cannot see the truck driver’s mirrors, assume the driver may not be able to see you. Pass only when it is safe, do not cut in sharply after overtaking, and give the truck room to change lanes or turn. K53 observation guidance emphasises mirror and blind-spot checks for safe movement; these principles are even more important around larger vehicles. Truck drivers also need active mirror use and planned manoeuvres, because their blind spots are larger and their vehicles respond more slowly. Road safety depends on both drivers making space and remaining predictable.

Frequently Asked Questions
Where are a truck’s blind spots?
They can be directly in front, along both sides and directly behind the vehicle or trailer.
How can I know if a truck driver can see me?
If you cannot see the driver’s mirrors, assume the driver may not be able to see you.
Should I overtake a truck slowly?
Overtake only when safe and complete the pass decisively without lingering beside the truck.
Why should I not cut in front of a truck?
The truck needs more distance to stop, and cutting in reduces the driver’s time and space to react safely.
