Carnage erupted at the start of the Grand Prix of Baltimore with a huge track blocking crash bringing out the red flag.

The problems started at the front when the Dyson Racing entry appeared to get a better start than the pole sitting Muscle Milk car alongside.

The P2 HPD of Scott Tucker checked up to avoid running into the the pole car but was hit from behind by the ESM entry of Anthony Lazzaro.

Things started to get ugly from there. The CORE Porsche slammed into Tucker’s spun car and in a bad day for the German brand – both other 911s also got caught up in the mess.

The Risi Ferrari and No.93 Viper were also left with nowhere to go.

All drivers emerged uninjured from the crash.

After an hour’s delay, the race is now set to go green with a sprint to the new checkered flag time at 6:00pm.
