what is the highest gear in car driving

Simple - - - Low 1st then 2nd - 3rd - 4th - 5th high. ( some modern cars even have a 6th gear).

However in snow - as there is less torque/traction in a 'higher gear. It would be better to try to move away in a higher gear - 2nd or 3rd - which should lessen the chance of the driving wheels spinning without 'grip'. (in the real world, it would possibly mean 'slipping the clutch' (Not letting the clutch fully engage until the car is rolling).

Note - it would be almost impossible to move a car off in a gear higher
than 3rd.


A low gear allows the engine to turn faster for a given wheel speed, producing more power, and multiplies the torque available at the wheel, so producing a greater tractive force between the wheel and the road. This means that the vehicle can either accelerate faster or pull a greater load than it could in a higher gear.

A high gear allows the engine to turn slower for a given wheel speed, reducing engine noise and fuel consumption (and allowing higher overall speeds within the engine's limited speed range), but with a corresponding reduction in tractive force between the wheel and the road. So the vehicle is quieter and more fuel-efficient, but cannot accelerate as quickly or pull as heavy a load as it could in a lower gear.
