DRAWBAR LENGTH - horizontal distance from the centreline of the towing pivot to the centreline of the leading 'Axle Group' of the trailer.

   DRIVE TRAIN - The vehicle components which transmit engine power to the driven wheels (ADR 28).

   DRIVER'S EYE POSITION – The position for eyes corresponding to the rearmost eye position on the '95th Percentile Eye Ellipse' (ADR 12).

   DRY BREAKING STRENGTH - the tensile strength of a webbing strap conditioned in an atmosphere at 20 ± 5°C and relative humidity not more than 67%.

   E - a nominal unit of 'Control Signal' strength which, for compressed air 'Brake Systems', is shown in the table below:

   Table: 'E' VALUES OF CONTROL SIGNAL STRENGTH
   Nominal Conversions
   0.0E Zero Compressed Air Energy Level
   0.15E 15psi   =  100kPa
   0.20E l9psi    =  130kPa
   0.24E 22psi   =  155kPa
   0.31E 29psi   =  200kPa
   0.65E 61psi   =  420kPa
   1.00E 94psi   =  650kPa
   1.06E 100psi =  690kPa

   For the purpose of ADR 35/.. and ADR 38/.. 1.0 'E' has been equated to the 'Nominal Minimum Energy Level' of compressed air brakes which for vehicles, has been nominated as 650 kPA. Values appearing in brackets after 'E' values in ADR 35/.. and ADR 38/... are the equivalent kPA values for compressed air 'Brake Systems'. The relationship between 'E' and the other brake control mediums has not been set in ADR 35/.. and ADR 38/...

   ECE REGULATION - (UNITED NATIONS ECONOMIC COMMISSION FOR EUROPE REGULATION) - an addendum to the United Nations Agreement Concerning the Adoption of Harmonized Technical United Nations Regulations for Wheeled Vehicles, Equipment and Parts which can be Fitted and/or be Used on Wheeled Vehicles and the Conditions for Reciprocal Recognition of Approvals Granted on the Basis of these United Nations Regulations. Also see UN REGULATION.

   ELECTRICALLY POWER-ASSISTED CYCLE (EPAC) - means an electrically-powered pedal cycle with a maximum continuous rated power of 250W, of which the output is:
         1.                 progressively reduced as the cycle's travel speed increases above 6 km/h; and
         2.                cut off, where:
 1.                  the cycle reaches a speed of 25 km/h; or
 1.                the cyclist is not pedalling and the travel speed exceeds 6km/h.

   EMERGENCY BRAKE SYSTEM: that part of the 'Brake System' which automatically applies in the event of trailer break-away.

   EMERGENCY LOCKING RETRACTOR - a retractor incorporating a locking mechanism that is designed to lock under abnormal operating conditions.

   ENGINE FAMILY - a basic classification of vehicles having similar characteristics as defined in clauses 37.4.3.1 to 37.4.3.2 of ADR 37/00 or clauses 7.3.1 to 7.3.2 of ADR 37/01.

   ENGINE FAMILY - means a basic classification of engines having similar characteristics as defined in ADR 36 clauses 36.3.4.1 to 36.3.4.4.

   ENGINE SPEED AT MAXIMUM POWER - ADRs 28/01, 39 and
