When does the braking distance increase?

The braking distance increases under specific conditions that affect vehicle dynamics.

1. **Driving down slopes:** When a vehicle is on a decline, gravity accelerates it, meaning it will take longer to stop because additional speed adds to the stopping distance.

2. **Carrying heavy luggage:** Extra weight from heavy luggage increases the inertia of the vehicle. This means that more force is required to slow down or stop, thereby increasing the braking distance.

Both conditions directly impact how long it takes for a vehicle to come to a complete stop, underscoring the importance of considering these factors for safety in driving. Proper awareness of these elements can help prevent accidents and ensure road safety, which is a central tenet of German traffic regulations.
