What should you do when parking on or along a highway during nighttime or moments of insufficient light?

When parking on or along a highway during nighttime or in moments of insufficient light, turning on your emergency flashers or lights is the most effective method for ensuring your vehicle is visible to other drivers. This action signals to approaching vehicles that there is a stationary object on the roadway, increasing safety for both you and oncoming traffic.

Using emergency flashers also works to alert other drivers to your presence, which can prevent accidents caused by drivers not seeing you parked on the side of the road. It’s a crucial precaution to take in low visibility situations.

While popping open the hood of the car might indicate a breakdown, it does not provide visibility to other drivers. Turning on your interior lights could help you see inside the vehicle but does not alert others to your presence. Using high beams is unsuitable in this context, as it could blind oncoming drivers rather than make your vehicle more visible. Thus, activating emergency flashers is the safest and most responsible choice when parked on or near a highway in low-light conditions.
