NEARLY half of all motorists admit to driving far too close to the car ahead while on motorways.
The shock statistic is revealed in a survey by Huddersfield road safety campaign Brake.
High-speed multiple crashes are the result of driving too fast, too close and leaving little thinking or reaction time.
Now, Brake want the `only a fool breaks the two-second rule' message again drummed into British drivers.
Leaving a two-second gap between your vehicle and the car in front should leave enough time to react.
In wet or foggy weather that time should be increased to four seconds.
On average, five people are killed and 50 seriously injured on UK motorways every week.
Brake chief executive Mary Williams said: "By not keeping a safe distance on motorways lives are being needlessly put at risk.
"Leaving a two-second gap is your braking space in an emergency.
"Failure to do this can have catastrophic results," she added.
