Final answer:
d. Only if using a turn signal
It is generally legal to approach a right turn while crossing over a bike lane as long as it's done with caution, giving right of way to cyclists, and with the use of a turn signal. Enhancing pedestrian safety at intersections can be accomplished with the introduction of a traffic signal, which also helps to control vehicle speed.
Step-by-step explanation:
When approaching a right turn that crosses over a bike lane, the legality of this maneuver depends on the specific traffic laws of the region you are in. Generally, it is legal to cross into a bike lane to make a right turn; however, there are important precautions and rules that must be followed. Drivers are typically required to ensure that the bike lane is clear of cyclists before merging into it and must use their turn signal to indicate their intention to turn. It's crucial to proceed with caution and give right of way to any cyclists present.
Regarding pedestrian safety at intersections, a common issue is that many students and others must dodge traffic to get across roads when coming to or leaving campus. The implementation of a traffic signal would address this problem by creating regular intervals at which pedestrians can cross safely. Furthermore, the presence of a traffic signal tends to reduce vehicle speed, as drivers are unable to speed through the signal, thus enhancing safety for all road users.
