When entering a highway, which action is most appropriate?

• A. Enter at or near the speed of traffic.
• B. Use mirrors and turn signals.
• C. Leave 3 seconds of space between you and the vehicle ahead.
• D. Merge into a space large enough for your vehicle to safely join the lane.

Answer: (D)

When you enter a highway, the priority is to complete the merge safely by having a space large enough for your vehicle to join the traffic. This ensures you can accelerate to match the speed of those already on the roadway without forcing others to brake or swerve. Before merging, check mirrors and blind spots, signal your intent, and adjust your speed to fit the gap. While keeping a proper following distance and signaling are important, they don’t by themselves guarantee a safe merge if there isn’t adequate room to enter. Entering at the right speed is useful, but only after you’ve found a sufficiently large space to safely join the lane.
