What is a safe driving technique when merging onto a highway?

Answer: B — Accelerate to match the speed of traffic

Accelerating to match the speed of traffic is a vital safe driving technique when merging onto a highway. This practice ensures that the vehicle entering the highway can integrate smoothly and safely with the existing flow of traffic. Merging at a similar speed significantly reduces the risk of collisions, as it minimizes the disruption to the vehicles already on the highway and allows for a more predictable movement for all drivers. When merging, a driver needs to assess the speed of vehicles in adjacent lanes and adjust their speed appropriately, enabling them to merge seamlessly into a gap without forcing other drivers to brake or alter their speed unexpectedly. This technique contributes to overall roadway safety by promoting a smooth transition and preventing potential hazards associated with drastic speed changes during merging maneuvers.
