The Transportation Security Administration (TSA) is warning truckers who cross the U.S.-Mexican border to make deliveries to be careful due to drug related violence around the area, according to Todaystrucking.com.

With more than 200 American slayings along the Mexican border since 2004, TSA's Highway Information Sharing and Analysis Center (ISAC) has issued the following guidelines for trucking companies and drivers with scheduled deliveries and/or pick-ups in or close to Mexico: 

• Report in with operations headquarters or dispatchers at every scheduled or non-scheduled stop. Provide dispatcher with detailed location and next destination information.

• Establish a duress code for the prescribed route that allows the driver to effectively communicate potential problems in the presence of potential criminals 

• Avoid driving on potentially unsafe roads and stick to the toll roads whenever possible. 

• And check with cell phone providers prior to departure to ensure that the driver's cell phone is capable of roaming on GSM or 3G international networks. 

Truck drivers witnessing potential criminal activities should contact Highway ISAC's First Observer program at 888-217-5902.
