Ask a Trooper

Question: First, thank you for sharing our concerns on traffic safety.  I see an increase in drivers not accelerating to enter the main flow of traffic, until they are on the main roadway.  This also happens, but less often, when exiting the main flow by slowing down before in the exiting lane.  This recently happened to my neighbor’s son who rear ended a car pulling onto the highway.  I would think that there would be accident data on these types of situations.  Thank you again for your service and for keeping us informed.

  Answer: Thank you. Let’s talk about this as it pertains to entering the freeway. Entry ramps are short, one-way roads that provide access to freeways. At the end of most entry ramps, there is an acceleration lane that allows you to increase your speed to safely merge with traffic already on the freeway.

  To avoid disrupting traffic flow or cutting off other drivers when you merge, adjust your speed to match the vehicles already on the freeway. You must yield to other vehicles when merging. Use your turn signal to let other drivers know your intention. 

  Do not stop on the ramp or in the acceleration lane unless it is absolutely necessary. When an acceleration lane is not available and a “Yield” sign is posted on the entry ramp, obey the sign. Stop if necessary. 

  When it comes to getting off the freeway, it is helpful to know where you need to exit the freeway before you begin driving. Watch for signs that provide information about upcoming exits. As you near your desired exit, signal your intent to change lanes and move into the deceleration lane when you can do so safely. This gives you time to slow down before reaching the exit ramp and helps you avoid obstructing faster-moving traffic.

  If you miss your exit, proceed to the next one. Do not back up or make a U-turn to return to the desired exit.
