How many seconds of gap is needed when crossing a two-lane roadway?

To ensure safety when crossing a two-lane roadway, a gap of 6 seconds is generally recommended. This gap allows for adequate time to assess the conditions of both lanes and to make an informed decision about crossing. The 6-second rule provides a buffer that helps a driver gauge the speed of oncoming vehicles and avoid potential accidents. This time also accounts for the deceleration of vehicles as they approach, allowing sufficient space for a safe crossing.

This spacing is particularly important in situations where visibility may be limited or where drivers may need to react quickly to changing traffic conditions. A shorter gap may not provide enough time to react if a vehicle approaches rapidly, while a longer gap may not always be practical in busy areas. Hence, this 6 seconds is a well-established guideline for safety when navigating such roads.
