If your car starts to skid what should you do first?

Answer 1

In Winter, I would try to turn the other way and brake.

In Summer, Definitely brakes.

Avoid the "lock up the brakes" panic style braking- if the wheels cannot revolve, you have no ability to steer.

Take foot off accelerator, turn into the direction of the skid (if back of car went to the right, turn to the right) and brake. We used to say "pump" the brakes, but anti-lock brakes now do that for you- keep a steady pressure on the pedal.
