Final answer:
The correct action when driving on a road with a single broken white line is to stay in your lane and only change lanes or pass when it is safe. Caution is essential, and drivers must abide by traffic signals and speed limits for road safety.
Step-by-step explanation:
When driving on a roadway with a single broken white line marking, the proper action to take is to stay within your lane. The broken white line indicates that you can change lanes when it is safe to do so, but it is not an instruction to change lanes whenever possible or to stop before the line. You may only cross over the broken line to pass slower vehicles if it is necessary and safe to do so after checking for traffic. It is important for drivers to follow traffic signals and speed limits to maintain road safety.
Caution is always advised, and stopping at the red traffic light is typically mandatory unless an extreme circumstance, such as a medical emergency, might justify cautiously proceeding. Remember, driving behaviors such as tailgating or speeding are unsafe and discouraged.When driving on a roadway with a single broken white line marking, you should stay within your lane.
