In what situation is stopping a vehicle on a freeway advisable?

Stopping a vehicle on a freeway is generally advisable only during an emergency, as freeways are designed for continuous and high-speed traffic. Emergencies may include situations such as engine failure, tire blowouts, or medical emergencies that require immediate attention. In these situations, it's essential to stop safely and quickly to prevent further danger or accidents.

The other situations can lead to hazardous conditions. For example, stopping due to fatigue is not safe while traveling on a high-speed road; it's better to pull into a rest area or a safe place before fatigue sets in. Similarly, stopping to let others pass is unnecessary on a freeway, as drivers should maintain their lanes and speed unless in a situation where it is dangerous to do so. Lastly, stopping during heavy traffic can create confusion and increase the risk of rear-end collisions, as other drivers may not expect a vehicle to stop unexpectedly in a fast-moving lane.
