Car Wanders On The Motorway
A car that drifts and needs constant small corrections at higher speeds usually has wrong tyre pressures, worn tyres, incorrect alignment or play in steering and suspension parts.
High risk
Have it checked promptly. Vague steering at speed reduces safety, especially in crosswinds and emergency moves.
Short answer · Why does my car wander on the motorway?
A stable car holds a straight line with little steering input. Low or uneven tyre pressures, worn tyres, alignment that is off, or play in track rod ends, ball joints and wheel bearings make the car follow ruts and drift. Crosswinds make it more noticeable. Worn shock absorbers add to the floating feeling.
