Explanation
Most expressways have an entrance ramp that allows you to accelerate and match the speed of traffic before merging. However, if the entrance lane is too short to reach expressway speed-or if there is no acceleration lane - you must stop and wait for a gap in traffic large enough to merge safely. This situation can be dangerous due to the increased risk of rear-end collisions and the need for rapid acceleration to enter traffic. Wait for a break that gives you enough space to reach cruising speed without disrupting the flow of oncoming vehicles. Then, signal your intention and accelerate quickly to blend in with traffic.
