A new survey has found that three-quarters of people get involved in arguments with their partner while travelling in a vehicle, making a good car insurance policy vital in case the distraction leads to an accident.
According to research by the Budget Car Rental company, the majority of arguments begin within an hour of the trip getting under way, with bad driving habits by a partner leading to nearly a third of the disputes.
More than a quarter (27%) of those questioned said the confined space of a vehicle sparks arguments.
Over a fifth (22%) said their partners' driving style discourages them from getting into a vehicle with them, while navigation and speeding also lead to friction between couples.
Other reasons for argument include back-seat driving and criticism of a driver's ability.
Stuart Liddle, spokesman for Budget UK, said: "Our research shows that many of us are embarking on road journeys without proper planning, which can result in arguments behind the wheel.
"It's always best to ensure you have a full tank before you set off and, with navigation causing the most arguments behind the wheel, invest in a GPS to ensure you get to your destination with minimum fuss."
