Final answer:
To ensure safety, you should maintain a safe following distance when behind another vehicle, especially in a motor home due to its increased stopping distance. Assessing the safety of crossing the road also depends on the speed of oncoming vehicles and their distance from you.
Step-by-step explanation:
When following another vehicle in a motor home, the correct action to take is to maintain a safe following distance. This is crucial for several reasons, including providing adequate time to react if the vehicle in front stops suddenly and to avoid collisions. Unsafe behaviors, such as tailgating or attempting to overtake without ample space, can lead to accidents. Moreover, maintaining a safe distance is especially important for larger vehicles like motor homes, which require more distance to stop due to their size and weight.
Considerations for crossing the road safely include assessing the speed of oncoming vehicles and the distance they are from you. If a car is 28 meters away, which equates to the length of about 8 cars, it is not necessarily safe to walk across the road without knowing the speed of the vehicle. Variables like the driver’s reaction time, the vehicle's speed, and your own walking speed contribute to the safety of crossing the road.
