More than three-fifths of UK motorists are not up to date with the Highway Code, according to the AA.
The motoring group’s survey of 13,327 members suggested 8,090 (61%) drivers had not read changes made in January.
Tim Rankin, managing director of AA Accident Assist, said the group was “concerned that so many still haven’t read the rules”.
He said: “While we are pleased that many of the changes can be successfully recalled, we’d like more drivers to know the rules outright so they can keep themselves and others safe.
“It is in everyone’s interest to take every measure that helps avoid collisions and remove confusion from the road, so we urge those that still haven’t read the updated code to do so as soon as possible.”
