(AP) -- A federal agency says a trucker from Jonesville is an "imminent hazard to public safety" and cannot drive commercial vehicles in interstate commerce.

The Federal Motor Carrier Safety Administration says 28-year-old Mark Isiah Gordon tested positive for amphetamines and methamphetamines after his loaded log truck hit a pickup truck head-on Oct. 1, killing three people.

Gordon could not be reached for comment Sunday. A phone company message said his number was disconnected.

The safety administration said in a news release Friday that its investigators and Louisiana State Police found that Gordon had been driving for more than the 14 hours a day allowed under federal safety regulations. The agency also found that his brakes were seriously deficient.

The agency didn't say how long he's barred or what appeals are possible.
