You are driving behind a large vehicle on a dry dual carriageway, keeping the standard minimum two-second separation gap. As continuous rain begins to fall, the road surface becomes wet, requiring you to double your separation distance in accordance with the Highway Code. Another car overtakes you and moves into the lane ahead, leaving you with an initial following time gap of 2.5 seconds behind it. By how many seconds must you increase your following time gap to establish the full recommended minimum separation distance for wet conditions?
Cevap: 1.5 seconds
Cevap
1.5 seconds
According to the UK Highway Code, drivers must allow at least a two-second time gap in normal dry conditions. On wet roads, tyre adhesion is significantly reduced and stopping distances are doubled, requiring a minimum following gap of at least four seconds (double the two-second rule). Since the current following gap behind the overtaking car is 2.5 seconds, the driver must ease off the accelerator to add another 1.5 seconds (), thereby establishing the safe four-second separation distance.
