An Abnormal Indivisible Load (AIL) is defined in The Road Vehicles (Authorisation of Special Types) (General) Order 2003 as:
“A load that cannot, without undue expense or risk of damage, be divided into two or more loads for the purpose of being carried on a road that –

(a) on account of its length, width or height, cannot be carried on a motor vehicle of category N3 or a trailer of category O4 (or by a combination of such vehicles) that complies in all respects with Part 2 of the Construction and Use Regulations; or
(b) on account of its weight, cannot be carried on a motor vehicle of category N3 or a trailer of category O4 (or by a combination of such vehicles) that complies in all respects with—
(i) the Authorised Weight Regulations (or, if those Regulations do not apply, the equivalent provisions in Part 4 of the Construction and Use Regulations); and
(ii) Part 2 of the Construction and Use Regulations."

In simpler terms, an Abnormal Indivisible Load (AIL) exceeds a gross weight of 40Te (on five axles), 44Te (on six axles) or with an axle load greater than 11.5Te.  The dimensions are also taken into account and any cargo exceeding 3m in width or 18.65m in length will be classed as an Abnormal Indivisible Load (AIL).  

In order to complete the transport of oversized cargo and abnormal loads up to 80Te notifications require two clear working days before the movement, increasing to five days for loads greater than 80Te.

• Loads over 3m wide require 2 clear days’ notice and permits
• Loads from 3.5m to 4.1m wide require 2 clear days’ notice, permits and an attendant or Pilot Car
• Loads 4.1m to 5.0m require 2 clear days’ notice, permits and an attendant or Pilot Car

A Special Order BE16 is required from the Highways Agency for any Abnormal Indivisible Load (AIL) which exceeds 6.1m in width or 30m in length along with 5 clear days' notice.
