If you notice that the vehicle deviates to one side when driving in a straight line, it may be due to...
A)Not keeping the steering wheel fully turned during manoeuvres.
B)A low brake fluid level.
C)Different pressures in the tyres of the same axle.Correct
Incorrect or unequal pressure in the tyres of the same axle causes the vehicle not to maintain a straight trajectory. The car will tend to drift to the side where the tyre has less pressure due to greater rolling resistance. It is crucial to check pressures periodically to ensure safety and proper vehicle behaviour.
