Rebuilding a following gap after another car moves in

A comfortable gap can disappear when another driver changes lanes in front of you.

A comfortable gap can disappear when another driver changes lanes in front of you. Treat that as a new situation to manage. You do not need to recover the space with a sudden reaction if a controlled adjustment can do it safely.

Understand the situation

Use the NSW safe-driving guidance to learn how following distance relates to conditions. Keep observing beyond the vehicle immediately ahead and ease your speed appropriately to rebuild space. More demanding conditions need more room, so a gap that felt adequate earlier may no longer be suitable.

Before you practise

• Notice the new vehicle without fixating on it
• Check traffic and preserve smooth control
• Rebuild a suitable gap for the current conditions

A focused practice session

During supervised practice, discuss changes in the gap as normal traffic develops. While parked afterwards, describe what triggered your adjustment and whether you reacted early. This is a judgment exercise, not a challenge to hold a fixed space against other drivers.

A situation to discuss

Another driver moves into the space you had been maintaining. Ease your speed appropriately and rebuild the gap while watching the surrounding traffic. Trying to defend the original gap can create the exact risk it was meant to reduce. Later, compare whether you noticed the lane change early enough to make a smooth adjustment. Look for an improvement in anticipation rather than a perfect gap that never changes.
