Final answer:
When driving on a four-lane highway and preparing to change lanes, check mirrors, indicate, perform a blind spot check, and merge when safe, while being mindful of traffic.
Step-by-step explanation:
When driving on a four-lane highway and you encounter a slow-moving vehicle in your lane, it is important to follow a specific procedure before changing lanes. First, you should check your mirrors and blind spots to ensure there is no oncoming traffic or vehicles in the lane you plan to switch to. Then, use your turn signal to indicate your intention to change lanes. Once it is safe, you can proceed to change lanes while maintaining a safe speed and distance from other vehicles.
When driving on a four-lane highway, before changing lanes to overtake a slow moving vehicle, it is critical to ensure roadway safety. The sequence of actions you should take includes: checking your rearview and side mirrors, turning on your indicator to signal your intention to switch lanes, looking over your shoulder for a blind spot check to ensure no vehicle is in the lane you wish to enter, and executing the lane change when it is safe to do so. Additionally, maintain awareness of the overall traffic flow and adjust your speed accordingly to merge safely into the next lane.
