What is a recommended distance to keep from other vehicles when driving?

Maintaining a distance of 3-4 seconds from the vehicle ahead is a recommended practice because it provides an adequate buffer space that enhances safety. This following distance allows drivers enough time to react to sudden stops or emergencies. By calculating the distance in seconds, drivers can adjust for variations in speed, road conditions, and visibility. If a driver counts three to four seconds from the moment the vehicle in front starts moving or stops until they reach the same point, they help ensure that they are not too close, thus reducing the risk of a collision.

In various conditions such as wet roads, heavy traffic, or low visibility, a longer distance may be prudent. The 3-4 second rule is particularly effective because it balances neither being too close, which risks collision, nor being so far that it may lead to congestion or unsafe driving behaviors.
