When is it illegal for a passenger while driving?

The situation described in the choice about riding on the bumper of a vehicle is illegal because it poses significant safety risks not only to the passenger but also to the driver and other road users. Passengers riding on the bumper do not have any protection and can easily fall off, leading to serious injuries or fatalities. Furthermore, this action can distract the driver and impair their ability to maintain full control of the vehicle, making it very dangerous.

Safety regulations emphasize the importance of passengers using proper seating within the vehicle, secured by seat belts, to ensure their safety and to minimize distractions for the driver. Passengers should be securely seated within the vehicle at all times.
