Check yourself before you wreck yourself with today's side deal: for $150, you get a 4.5-hour defensive driving class at In Control Crash Prevention Training (a $299 value). In Control has locations in South Weymouth, North Andover, Worcester, and Cape Cod; check the schedule to find a time and place that works for you.

In Control's titular crash prevention curriculum combines classroom and real-life instruction. During the 4.5-hour tutorial, expert instructors will explain how to best use your brakes and how to handle highway emergencies. A racecar driver will teach you how to keep control of the car as you slam on the brakes while driving at highway speed. You'll also learn how distractions affect your driving and receive expert tips for controlling your ability to stay moored upon this good, paved-over Earth. Using the company's vehicles, you'll be able to test your own reflexes and self-control on In Control's closed course.

In Control's teaching staff is made up of experienced racecar drivers, so they know more than a thing or two about turning left and dealing with aggressive drivers. Every technique In Control teaches was specifically developed to respond to the most common types of accidents, the same guidance that police and emergency responders receive during their training. Many insurance agencies offer up to a 10% discount on their rates as a reward for completing the course.

If it's been more than 10 years since you first glimpsed seminal drivers-ed classics such as Brain Jelly, Road Toast, The Semi Ate My Daughter, or Friends Don't Let Friends Die Drunk, let In Control Crash Prevention Training refresh your memory without the scare tactics or mid-80s production values.
