Why is it important to look both ways when entering a one-way street?

Looking both ways when entering a one-way street is crucial primarily for safety reasons, particularly to remain aware of any vehicles that may be turning onto the street from adjacent roads. While a one-way street typically means traffic is only flowing in one direction, it does not eliminate the possibility of vehicles approaching from different directions, especially if they are making turns. By checking both ways, a driver can ensure that there are no surprises as they merge onto the one-way street, which enhances overall road safety.

The importance of this practice extends beyond just avoiding collisions with turning vehicles; it also contributes to being aware of other road users, including pedestrians and cyclists, although that is not the primary focus of the correct answer. In essence, looking both ways is a critical habit that promotes defensive driving and helps prevent accidents.
