What should you do when entering an expressway?

When entering an expressway, the correct approach is to accelerate in the acceleration lane and merge carefully. This is because acceleration lanes are specifically designed to allow drivers to increase their speed to match the flow of traffic on the expressway. By doing so, you can safely merge into the traffic without disrupting the flow or causing hazards for other vehicles.

Accelerating to the appropriate speed ensures that you can integrate into moving traffic smoothly. Careful merging involves checking mirrors and blind spots to confirm that the lane is clear before making the transition. By following this method, you contribute to safer traffic conditions and enhance your own safety as well.

The other options suggest actions that could lead to unsafe situations. For instance, slowing down and waiting for a gap in traffic can create confusion and potential collisions, while stopping and yielding could cause traffic disruptions and increase the risk of accidents. Changing lanes immediately without checking for other vehicles can also be dangerous, as it may lead to merging conflicts. Thus, the strategy of accelerating in the designated lane is the safest and most effective approach when entering an expressway.
