Visibility, blind spot, turning, vehicle dynamics, braking distance, mountains and tunnels
Heavy vehicles have large blind spots, so N2 and N3 need front, wide-angle and close-proximity mirrors. Special duties of care apply when turning, reversing and moving off; braking distance and centrifugal force grow with the square of the speed, and special rules apply on mountain roads and in tunnels.

From the key facts
- Ordinance on Technical Requirements for Road Vehicles (VTS) Art. 112: exterior rear-view mirrors on the left and right with a view 100 m to the rear; N2/N3 additionally a front mirror (not N2 up to 7.50 t), wide-angle mirrors on both sides and a close-proximity mirror on the side opposite the steering wheel.
- Traffic Rules Ordinance (VRV) Art. 13 para. 5–6 and Art. 17: swinging out only with particular care, stopping if necessary; with a load that obstructs the view or no view to the rear, a person to guide you; reverse only at walking pace, never over level crossings.

Question 1: How far back must the driver of a motor vehicle at least be able to see the carriageway beside the body easily with the exterior rear-view mirrors?
- 50 m
- 25 m
- 100 m
Show answer
Correct answer: 100 m
VTS Art. 112 para. 1: motor vehicles must have one rear-view mirror on the outside on the left and on the right, allowing the carriageway beside the body and to the rear to be seen easily for at least 100 m. 50 m or 25 m is too little.
Legal reference: VTS Art. 112 para. 1
Question 2: What applies when reversing?
- You may only drive at walking pace; reversing over level crossings and junctions with poor visibility is prohibited.
- With a reversing camera, reversing at up to 20 km/h is allowed.
- Reversing over level crossings is allowed if the barriers are open.
Show answer
Correct answer: You may only drive at walking pace; reversing over level crossings and junctions with poor visibility is prohibited.
VRV Art. 17 para. 2: you may only reverse at walking pace; reversing over level crossings and road junctions with poor visibility is prohibited. A camera does not cancel this rule.
Legal reference: VRV Art. 17 para. 2
Question 3: Aylin's truck has no view to the rear. When must she call in a person to guide her when reversing?
- Only if the vehicle is longer than 12 m
- If not all danger is excluded
- Only in built-up areas on public roads
Show answer
Correct answer: If not all danger is excluded
Under VRV Art. 17 para. 1, for vehicles with a restricted view to the rear, a person must be called in to guide the driver when reversing unless all danger is excluded. The location or the vehicle length is not decisive.
Legal reference: VRV Art. 17 para. 1
