National Auto Sport Association Northwest Haunted Horsepower weekend at The Ridge Motorsports Park in Shelton, WA. The Ridge is a 2.47-mile, 16-turn road course on the Olympic Peninsula, known for its technical layout, elevation changes, and stunning surroundings. The event offers four participation formats:

**High Performance Driving Education (HPDE)** gives drivers the opportunity to learn and develop track driving skills in a safe, professionally staffed environment. Four experience levels are available — HPDE 1 guarantees an in-car instructor for drivers new to track events; HPDE 2 is for drivers signed off to run independently at HPDE 1 speeds; HPDE 3 builds toward more open passing by the end of the weekend, with Sunday continuing where Saturday left off; HPDE 4 is for advanced drivers with open passing and requires pre-approval from the Chief Instructor. Passengers are permitted in HPDE 3 and 4 with group leader approval for passengers 18 and older. Drivers who have not participated in a NASA HPDE 4 event within the last two years and do not hold a valid NASA license must contact [email protected] for screening and approval before registering.

**Time Trial** is for licensed competitors running against the clock. Open to a wide range of vehicles — production cars, converted race cars, prototypes, and electric vehicles — with weight-to-horsepower ratios used for fair class structure. A current NASA Time Trial license is required. Drivers who have not participated in a NASA Time Trial event within the last two years must contact [email protected] for screening and approval prior to registering.

**Sprint Racing** is wheel-to-wheel competition in a friendly, sportsmanship-focused regional race series. A current 2026 NASA Competition License and approved medical on file with NASA are required. Drivers who have not participated in a NASA race group event within the last two years must contact [email protected] for approval prior to registering.

**New Racer Competition School** is available for advanced HPDE drivers or drivers with prior racing experience who want to obtain their NASA Provisional Racing License. The school covers race starts, restarts, side-by-side driving, and flag review. Prospective participants must create a NASA profile, submit a Provisional License Application, and receive approval from the event directors before registering.

**Pro Pass** upgrade includes early entry, priority parking, a morning track walk with the Chief Driving Instructor, and access to the NASA Lounge with snack bar.

NASA membership is required for all participants ($79/year). Registration at track includes an additional $50 fee. Register in advance at members.drivenasa.com.
