For the 2005 race DARPA has said the course will be at most 175 miles As for roads because of environmental restrictions outside of their control the desert tortoise for example all or most of the course is over dirt roads The course can and most likely will cross active roads In last year s competition one team was paused to allow a truck to cross the road The only external control allowed actually its required is a 3 way control RUN PAUSE and STOP If the vehicle is paused the timer stops running for that team until they start running again 12 08 6 Jun 2005 UTC
