Don't drink and race!
The Dos Mares 500 organizer specifically brings that to attention of participants: An breathalyzer test is mandatory for all pilots without exception before the false start. (Saturday before noon)
It is recommended NOT to consume alcoholic beverages one day before the competition, because there is a risk of still giving a positive result in the test.
Drivers that test positive will not be allowed to start!
They will also not be refunded the registration fee's.
