A burning car sparked a vegetation fire on the Cuesta Grade on Saturday morning, according to the CHP.
The car fire on northbound Highway 101 was first reported about 7:55 a.m., with nearby brush catching fire soon after. Two northbound lanes were being closed about 8:05 a.m. near Mt. Lowe Road about halfway up the Grade.
About 8:35 a.m., Cal Fire reported the fire had grown to about 3 or 4 acres, with the fire burning uphill against the wind. The San Luis Obispo City Fire Department was assisting Cal Fire.
This is the second fire on the Cuesta Grade sparked by a burning car in about a week.
On July 7, a Mercedes-Benz sedan caught fire about 4:20 p.m. on northbound Highway 101 near the Cuesta Grade summit. That fire burned about 60 acres before it was contained on July 8.
