LEHIGH VALLEY, PA (May 20, 2009) – Mack Trucks, Inc. will again sponsor a Driving Skills Safety Challenge during the WasteExpo 2009 show. The competition will be held in the Silver lot #4 next to the Renaissance Hotel outside the Las Vegas Convention Center on June 9 and 10, 2009. The competition runs from 9 a.m. to 4 p.m. on Tuesday, June 9, and from 9 a.m. to 3 p.m. on Wednesday, June 10.

The competition is open to any driver at least 18 years of age with a valid CDL who shows proof of operator training, and is registered for the show. This year’s event will include individual and team competitions (two operators per team).

Contestants will operate their choice of MACK® TerraPro™ Low Entry and Cabover models in a closed course set up to simulate actual refuse conditions. Operators must complete a pre-operation safety check and successfully navigate the skills course. Each individual will have one (1) attempt. Scoring will be based on accuracy and adherence to safety procedures. Specific scoring rules will be provided at the event.
