When nearing a curve or the crest of a grade, how far must another vehicle be visible before turning?

When approaching a curve or the crest of a grade, the law requires that the driver of a vehicle must be able to see at least 500 feet ahead before making a turn. This distance is crucial for ensuring safety on the road, as it allows the driver to assess whether the roadway is clear of oncoming traffic, pedestrians, or any obstacles that may pose a danger during the maneuver.

Visibility of 500 feet gives drivers adequate time to react, as well as ensures that they are not caught off-guard by any vehicles that may be approaching at higher speeds. It is particularly important in situations with limited visibility, such as curves and hills, where the driver’s line of sight is obstructed. Following this guideline enhances road safety by reducing the likelihood of collisions and ensuring drivers have sufficient time to make thoughtful decisions based on the conditions ahead.
