When the Secretary of Homeland Security issues an elevated or imminent alert, the following steps should be taken:

On the Road:

• Be alert when driving. Look for vehicles following you, especially if there are 3 or more people in the car. If you believe you are being followed, call your dispatcher or 911 immediately.
• When leaving your facility, be aware of any possible surveillance of your facility or your truck.
• Don't discuss your cargo, destination, or trip specifics with people you don't know or on open channels.
• When stopped at a traffic light or in traffic, be aware of anyone approaching your vehicle.
• Make sure you have communication devices to contact your dispatcher and emergency officials. Carry a back-up if possible.

Stopping at Facilities:

• Leave your truck in a secure parking lot or truck stop if possible; if not, be certain someone can watch your vehicle.
• Never leave your vehicle running with the keys in it; shut off the engine and lock the doors.
• If possible, don't stop in unsafe or high-crime areas.
• Use seals or other methods to prevent and identify tampering.
• Don't preload hazardous materials shipments without adequate security.

Protecting Your Vehicle:

• Use an engine kill switch
• Use tractor and trailer brake locking devices
• Check your electronic tracking system regularly and notify your dispatcher when it's not working or tampering may have occurred.
• If you drop a trailer, use a fifth wheel lock whenever possible.
• Perform a quick walk-around to check your vehicle for foreign objects after all stops.
