Motorists have been urged to give their full attention to the road after a new survey suggested many drivers are not concentrating during their journey.
While drivers might be slightly annoyed to discover they have missed a turning on their journey, a motoring organisation said the error is a sign of a much more serious issue - namely that motorists are making their way to their destination on autopilot.
Zoning out could have serious consequences, including a possible accident, which in turn could lead to a jump in the motorist'scar insurance premiums.
The Institute of Advanced Motorists (IAM) survey found one in 10 drivers are often unable to remember their entire car journey, while more than half have missed a turning because they were distracted.
It found drivers aged 18 to 25 are the most likely to be in danger of distraction, with a third admitting they could not recall any part of their journey often or quite often.
RAC spokesman Simon Williams said: "Concentration is an essential and critical part of driving, but we all know it can be difficult to maintain focus on one particular task for a length of time, especially on familiar roads like the commute to work or long and monotonous journeys.
"The mind wandering is probably the single biggest obstacle to maintaining concentration, which, along with numerous other distractions that present themselves on the road, can make it far more difficult to maintain the optimum concentration level."
