Drivers warned of costly common mistake you may be making when stuck in traffic

The RAC has warned motorists that a common practice when travelling in traffic could have dire consequences for their vehicle.

When stuck in a traffic jam, drivers typically change gears more frequently, meaning that many leave their hand on the gearknob.

However, in a blog on the company's website, the RAC warned that applying too much pressure could lead to significant damage to the gearbox.

They explained: "The gearstick is connected to a selector fork, which is designed to make contact with a rotating collar for a short amount of time.

"If you rest your hand on the gearstick, you risk applying pressure to the selector fork, causing premature wear."

When accelerating, it can be quicker and more convenient for drivers to keep their hand on the gearknob, shifting gears as soon as they can.

However, drivers who insist on doing this must make sure that they do not apply a considerable amount of pressure, which could wear out the selector fork.

If the component needs replacing, drivers could face a repair bill of several hundred pounds in order to get back on the roads.

The RAC suggested that drivers should consult the handbook that came with their vehicle to see whether they are able to rest their hand on the gearstick.

They added: "Some owner's manuals specifically advise against resting your hand on the gearstick, it's worth checking yours to see if that's the case."

Motorists were also advised to keep both hands on the steering wheel wherever possible to maintain full control of their vehicle.

In addition to resting a hand on the gearstick, the RAC's blog also reminded motorists who own an automatic car to avoid shifting from reverse to drive whilst the car is still moving.

They advised: "Shifting between reverse and drive (and vice versa) in a car fitted with an automatic gearbox is really bad for the transmission.

"Shifting gear before coming to a stop will cause wear and tear on the transmission band, rather than the brake discs and pads, which are serviceable items. Any work on the automatic transmission will be labour-intensive, and therefore costly."
