Final answer:
When finding a stopped car in your lane with no room to stop, steering to a clear left lane is often the safest choice. Otherwise, checking for an escape path to the right or applying hard braking to reduce impact severity is advisable, while avoiding oncoming lanes unless absolutely clear.
Step-by-step explanation:
If you are driving in the right lane of a four-lane undivided road and come over a hill to find a car stopped ahead in your lane with no room to stop, the best option would depend on the situation at hand. If possible, steering into the left lane may be the safest option if it is clear and allows for a smooth lane change. However, this maneuver should only be executed if you are certain that you can do so without causing a collision. Steering into the oncoming lanes is generally quite dangerous and should be avoided unless there's clear visibility and assurance that there are no oncoming vehicles. Steering to the right to find an escape path on the shoulder is another potential option, especially if there is no other suitable space on the road to maneuver safely without causing harm to others. Importantly, while hard braking may not avoid a collision entirely, it can significantly reduce the severity of an impending collision. Remember, safety and the avoidance of risk to others should be the primary concern in all driving decisions.
