When should you cut your speed in half when driving?
You should reduce your speed by 1/3 on wet roads and by 1/2 or more on snow packed roads (i.e., if you would normally be traveling at a speed of 60 mph on dry pavement, then on a wet road you should reduce your speed to 40 mph, and on a snow-packed road you should reduce your speed to 30 mph).
Does speeding actually get you there faster?
