Final answer:
It is crucial to watch out for motorcycles when coming out of a side road because they have a smaller profile, making them harder to see and their speed more difficult to judge, which can lead to severe accidents due to their vulnerability on the road.
Step-by-step explanation:
When you are waiting to come out of a side road, it is important to watch carefully for motorcycles because they are smaller and less visible than cars. Motorcycles can easily be obscured by other vehicles, or blend into the background, making them harder to spot. Additionally, the speed and distance of an approaching motorcycle can be more difficult to judge compared to larger vehicles.
Motorcycles have a much narrower profile, and because of this, it is essential to pay close attention to ensure that you do not pull out in front of a motorcycle that you did not see. Failing to notice a motorcycle can lead to serious accidents, as motorcycles and their riders have less protection than car occupants, making collisions particularly dangerous for motorcyclists.
