The moment an emergency call is dispatched it is a race against time. For the crew and ambulance every second counts. Therefore, it is essential that they are equipped with everything needed to handle a large variety of circumstances in a timely manner.

Snowstorms, they are likely to happen 

It is time to hit the road, but you know there's a good chance you will encounter a snowstorm on the way to your destination... You know the objective is to reach your destination safely and on-time. At some point along the journey your truck is going to need tire chains applied to the road surface. You have two options in this situation; get out of the vehicle and chain your tires up (while traffic is driving past you) or use automatic tire chains by flipping a switch from the comfort of you cab.
