Company car drivers spend up to 11 days in traffic congestion every year, a new survey has claimed.
Motor breakdown cover provider RAC says that during an average working week, a driver could spend two hours in traffic.
This is despite one-third of respondents resolving to spend less time travelling to work in the new year.
Employees are increasingly petitioning firms to allow them to work from home in order to cut driving hours down, the RAC claims.
But the survey shows that 50 per cent of companies are "not at all" supportive of drivers taking up flexible working practices.
RAC's executive director, Edmund King, said that companies were risking the lives of their employees by asking them to spend excessive amounts of time travelling to meetings.
Referring to statistics that one in ten company car drivers admits to falling asleep at the wheel, he said: "Too much time is wasted sitting in traffic jams. Companies and drivers need to get smarter to avoid congestion. Highway authorities need to do more to clear the bottlenecks.
"Perhaps due to extra hours stuck in congestion an astonishing ten per cent of drivers admit to falling asleep at the wheel. They are lucky they have lived to tell their tales."
