The answer is True. Always check behind you for approaching bicyclists before opening the driver's door.
Step-by-step explanation:
In regard to the question about looking behind you for approaching bicyclists before opening the driver's door, the answer is True. It is essential to always check for approaching bicyclists before opening the door to avoid accidents and ensure the safety of both the driver and the cyclist. This practice is known as the 'dooring' or 'getting doored', and it can result in serious injuries or even fatalities for the cyclist.
It is important to remember that bicyclists are more vulnerable compared to vehicles, and they may not have much time to react if a door suddenly opens in their path. By checking behind you, you can take necessary precautions to prevent such incidents from occurring. This is a crucial aspect of promoting road safety for all users, including bicyclists.
