What is an Abnormal Load?
A simplistic definition of an Abnormal Load is a consignment that is not normal. Having said that, to most people, it refers to cargo that results in the truck being oversized and overweight, whether that’s too long, too wide, too tall, too heavy, or a combination of these factors.
In more recent times, when categorising cargo, the expressions OOG (Out of Gauge) or OS (Over Size) have come into play.
In any event, you may be wondering: what is the maximum length, width, height, or weight permitted? With a standard truck, throughout the UK and Europe (with a few exceptions), there are clearly defined, universal limits – the most common being the maximum length of a standard trailer at 13.60m. Regrettably, the same does not apply to Abnormal Loads, where the maximum dimension/weight permitted varies from country to country and, in some cases, region to region.
What are the challenges of transporting abnormal loads?
Geographical variations in rules, regulations, and limits
In certain countries, an absolute legal limit applies, whereas elsewhere, movements require approval from the local highway authority, typically assessed against factors such as vehicle configuration, route choice, and timing.
Infrastructure Limitations
Narrow roads, low bridges, overhead cables, and restricted access points can all limit the routes available for abnormal loads, often requiring detailed surveys or alternative routing.
Traffic Disruption
Because abnormal loads move slowly and may take up more than one lane, they can cause significant traffic delays, meaning movements must be carefully timed to minimise disruption.
Specialist Equipment
Oversized or heavy cargo often requires purpose-built trailers, lifting gear and support vehicles, along with operators trained specifically for abnormal load handling.
Weather Delays
High winds, poor visibility or heavy rain can make moving heavy, large or tall loads unsafe, resulting in delays until conditions improve.
Higher Risk of Damage
Due to their size, weight or unusual shape, abnormal loads require precise lifting, securing and handling to avoid costly damage during transport.
