Dial #399 for roadside assistance...
As it turns out, maintaining roadside phones for stranded motorists isn't very cost effective, especially when 90% of drivers carry cell phones with them. Starting July 1st, Metro and the Los Angeles County Service Authority for Freeway Emergencies (LA SAFE) will begin a non-emergency road side assistance cell phone number (#399) for LA County highways. If you already have AAA the operator will forward you there and if not you will receive assistance from the Metro Freeway Service Patrol.
