While driving, how can you safely check whether the road is icy?

To safely check if a road is icy, it's important to understand the risks involved. The first choice, applying the brakes at a very low speed, is correct because it allows you to feel how the vehicle responds without losing control. If the car skids, it indicates icy conditions.

The other choices, jerking the steering wheel or rapid acceleration, are unsafe. Jerking the steering wheel can lead to loss of control, and accelerating quickly can make it difficult to gauge traction.

In terms of German traffic regulations, drivers must ensure they maintain control of their vehicle at all times. Checking for ice through gentle braking aligns with the principle of safe driving in potentially hazardous conditions.
