HOOKED ON DRIVING – Northern California / Reno Region

Hooked On Driving is a leading provider of performance driving programs, commonly known as an high performance driving experience (HPDE), or high performance driving school (HPDS). In the NorCal-Reno region, these programs are run on Track Days, at tracks such as Thunderhill Raceway, Laguna Seca, Reno-Fernley, and Sonoma Raceway (formerly Infineon, formerly Sears Point). We give drivers of high performance cars and sports cars the opportunity to drive their cars on a race track. During the first sessions a coach will ride in the passenger seat, and teach the driver high performance driving techniques.

All new drivers need to participate is a helmet (available rentals), and an inspection to be sure their car is roadworthy. Beginners are given a thorough briefing and are introduced to their coach before they drive their car on the track. The initial “A Group” for beginning HPDE drivers, teaches smoothness, awareness, and driving a proper, safe and efficient line on track. A priority is also placed on learning basic car control skills such as late braking, proper shifting and understanding the concept of the apex of a turn. While A group has significant passing restrictions to maintain a conservative pace, the B – Intermediate, C – Advanced, and D – Race-prepped groups have progressively more flexible passing rules and advanced level coaching.

There is NEVER any competition – wheel to wheel or timed laps – in our programs. Hooked on Driving HPDE Programs are safe experiences for all, an enjoyable time for every driver – and to assure that our drivers come away with much more confidence in handling their car in an emergency situation. Hooked On Driving customers frequently are heard saying that they’ve had, “The time of their lives!”.
