Tanker Haulage
In the European Union and non-EU countries that have signed the ADR agreement, tractor units which haul tankers carrying flammable liquids must be specially modified to reduce the fire risk. This includes using a fully insulated electrical system (neither side earthed to the frame), relocation of exhaust components, and enclosing all wiring in conduit. Additional requirements include mandatory ABS on both the tractor and the trailer, additional 6-kilogram (13 lb) fire extinguishers for putting out a fire in the tanker, leak containment equipment, etc.
In countries that have signed the ADR agreement, a driver is required to have special training for hauling dangerous goods (including flammable liquids) in tanks. This is a supplement to the main ADR training certificate.
