Driving and Parking Rules for Hazardous Materials

Driving rules for hazmat focus on reducing risk: avoid congested areas, tunnels, and heavily populated zones when possible; use the safest route. Parking rules are a favorite exam topic. Never park a placarded vehicle within 5 feet of a roadway, and never park within 300 feet of an open flame, bridge, tunnel, or place where people gather. When parking a placarded vehicle, keep it attended unless you are within a secure area; if unattended, use the parking brake, set chocks, and ensure it cannot be moved by unauthorized persons. Smoking and open flames are prohibited near hazmat. Following distance should be increased-at least one second per 10 feet of vehicle length plus a second, and more in poor conditions. Speed should be reduced. Traps: questions claim you may park under a bridge (no), or that you can smoke if windows are closed (no). Also know that retail parking lots and rest areas may be restricted. Rule of thumb: 5 feet from the roadway edge, 300 feet from fire/bridge/tunnel/crowds. Worked example: You must stop for the night with a FLAMMABLE placard. Park in a secure lot at least 5 feet from the roadway and 300 feet from any open flame or bridge; set the brake and chock the wheels.
