Various third-party delivery companies have pledged to keep their motorcycle couriers and other road users safer in London by signing a voluntary charter with the capital’s Transport for London (TfL) authority Tuesday.

Uber Eats, Deliveroo, Getir, Just Eat, and Stuart all signed the charter, consisting of 10 road safety principles.

These include ensuring couriers meet the legal requirements for working and riding in the U.K. and supporting them in understanding how to ride safely within the law, as well as realistic delivery schedules. The principles also work to support couriers in ensuring that vehicles are legally compliant and roadworthy.

In recent years, delivery on motorbikes, electric bicycles and mopeds have increased significantly in London and other cities, spurring concerns of citizens and authorities as riders often try to complete orders as quickly as possible.

“People are tragically losing their lives in avoidable motorcycle collisions, which all too often also injure or kill other road users. This is why we’re working closely with delivery, courier and servicing companies to address these sources of road danger and protect the lives of riders and everyone else on London’s streets,” said TfL’s chief of safety, health and environment officer Lilli Matson.

“We’re really pleased to have secured the backing of some of the biggest names in the sector for our charter, who recognize the part they can play in helping to create safer roads for everyone,” she added.

People riding motorcycles face the greatest likelihood of death or serious injury. Motorcycles, mopeds and scooters account for around 27 percent of deaths and serious injuries from 2017-2021 in London, with around 30 people killed each year, according to the TfL.

In the U.S. concerns on courier traffic safety remain top of mind, as like-accidents have increased since service saw peaks during the pandemic.

According to the U.S. Bureau of Labor Statistics, delivery drivers and related professionals were involved in more than 1.5 million accidents in the U.S. in 2022. In New York City, bicycle accidents for both delivery personnel and everyday riders are seeing a staggering increase, up 20 deaths this year alone, causing advocates to push for better bike lane infrastructure on roadways.
