Requirements for a car : winter and highways?

Question

My friends are planning on driving in from Ontario to Manitoba (about 24 hours driving, non-stop) and the highways are always brutal in the winter. Our winters are really cold and super icy, and I know that Ontario's aren't too much better. The person driving doesn't have enough money for a brand new car as he just got his license, but what would be some improvements on a car that would avoid accidents at the most? Like, chains on the wheels, etc etc. Please let me know, thanks!

Answer 1

Studded snow tires on all four corners. Nothing helps on your car if te tires can't stick to the road

Answer 2

1. Have the vehicle completely checked over by an automotive shop before you go.

2. Change all fluids.

3. By a set of snow chains.

4. Drive 2 to 3 hours and take a break.
