Ready to go wheel-to-wheel racing? Take this class to get your provisional license. You will learn the nuances of "race craft" to make you comfortable with starts, resumptions, various flag conditions, and what to do when a safety car is on track. You end the weekend with a few practice race starts so you are ready for your first real race upon graduation. Note- Must be HPDE 4 level driver to enroll. Send driving history to fooshe@aol.com after enrollment.
HPDE / TT INFORMATION:
All HPDE classes (1-4) on Saturday and Sunday.
ALL participants in the TT run group are REQUIRED to have a transponder.
Additionally, all drivers registering for HPDE4/TT must be pre-approved by the group leader prior to the event. If you have not participated in NASA SoCal HPDE4/TT within the last two years and do not have a NASA Competition racing or TT license, you MUST e-mail socal@drivenasa.com for screening and approval.
DIGITAL WAIVER:
NASA has moved to a digital waiver system that is required for ALL participants. Upon registering for an event, a text message will be sent to the mobile number configured in your account. Please follow the instructions and sign the digital waiver as soon as you get the text message. There is no need to wait until the day of the event - it can be done immediately. Failure to complete the digital waiver may delay your ability to get on track with your run group. Please make certain the number (1-707-210-0445) is not blocked on your device. We also use this number for keeping drivers updated during the event.
PLEASE NOTE TRANSPONDER RENTAL POLICY: Unfortunately, due to 25% of rented transponders not being returned, we have been forced to implement a $50 penalty on transponders that are not returned to Registration on Sunday, 30 minutes after the last session. On Monday morning, anyone who has a missing transponder will be charged $50 to their credit card on file. If the transponder is not returned to NASA SoCal (see Contacts page for address) by the Wednesday after the event, a replacement fee of $400 will be charged.
Also please note that transponders are not rented to HPDE1 and 2 groups as they are not timed but are REQUIRED in TT. Thank you for your understanding and cooperation.
INFORMATION FOR MINORS:
All minors are required to have parent or guardian present at the track to sign and submit the minor waiver. Each waiver is only good for THAT specific event. A new waiver is required for each event. Additionally, a parent or guardian MUST be in attendance for the entirety of the minors participation. Minors are not permitted to drive without a parent or guardian present. NASA 2025 CCR's section 3.5.
INFORMATION FOR CONVERTIBLE VEHICLES:
