Here's What A Professional Vehicle Tester Keeps In His Bag

It is safe to say that most people would envy driving the newest, fastest cars for a living. That is precisely what our friend K.C. Colwell does as the deputy testing director for Car and Driver magazine, as well as one of the drivers for their annual Lightning Lap track test. He has quite the resume!

We asked K.C. about his favorite gear for inside the car and his work bag — his answers might surprise you. So, to help you become a supercar tester, we've collected some of this gear. The professional says so.

Here's a look into the essentials that a professional vehicle tester carries with them. A digital voltmeter, a circuit tester, a test light, jumper cables, and a tire pressure gauge are among the most important tools for any vehicle tester. By having these tools on hand, they can properly inspect any vehicle for potential problems.
