What should a driver do before merging into traffic?

Answer: A — Check mirrors and blind spots, and signal their intention

The correct action for a driver before merging into traffic is to check mirrors and blind spots, and signal their intention. This safety protocol is essential for several reasons. Checking mirrors ensures that the driver is aware of other vehicles that may be approaching from behind or next to them. Blind spots, which are areas that are not visible in mirrors, can hide vehicles, making it crucial for a driver to look over their shoulder to confirm that the lane is clear. Signaling is equally important as it communicates the driver’s intention to merge to other road users, promoting awareness and allowing other drivers to adjust their speed or position accordingly for a safer merging process. This practice not only enhances the driver's safety but also contributes to the overall flow of traffic by reducing the chances of accidents during the merge. In summary, the action of checking mirrors, blind spots, and signaling ensures informed decision-making and fosters safer driving conditions for everyone on the road.
