Adelaide's latest technology trial has had an early mishap after a van carrying a load of e-scooters rolled in the CBD.

Key points: The Lime e-scooter trial began in time for the Adelaide Fringe festival

Police allege the driver of the van ignored a red light before the crash Lime says it is "relieved" no one was critically injured

Police attended the crash scene at about 1:30am at the intersection of King William Street and Grenfell Street.

SA Police said the driver of a Toyota Hiace, which was carrying a number of Lime e-scooters, allegedly ignored a traffic signal and rolled after colliding with a four-wheel drive.

The van driver, a 21-year-old Christies Beach woman, was issued with an expiation notice for disobeying a traffic light and both vehicles had to be towed.

In a statement, the company's director of government strategy Mitchell Price said the incident was not expected to delay access to e-scooters in Adelaide.

"We are relieved to hear no one involved in this incident was critically injured," he said.

"We have been in touch with the local authorities and will continue to assist in any way we can."

Trial for Adelaide Fringe festival underway

Earlier this month, urban mobility company Lime launched its pilot program in South Australia.

The US tech company has already secured 150,000 users in Brisbane and revealed plans for a fleet of 500 electric scooters to be ready in time for the Adelaide Fringe festival.

Recently, the company reached 500,000 rides since its launch in November.

Earlier this month, Mr Price said the pilot would be a step towards more accessible, greener forms of transport for South Australia.

"We know that Adelaide is the most car dependent city in Australia with growing traffic congestion," Mr Price said earlier this month.

"Our reliance on personal vehicles is threatening the dynamism of city living and the trend cannot be allowed to continue, which is why we are so excited to provide this much-needed transport alternative to the city."

E-scooters require users to download an app which allows them to be digitally unlocked, and charges a fee of 30 cents per minute of riding.

While they are only designed to travel up to 23 kilometres per hour, questions have been raised about the potential hazard they pose to pedestrians, how the vehicles should be classified, and whether the scooters could go the same way as failed bike-sharing schemes.

'Juicers' collect scooters daily

E-scooters already operate in more than 100 towns and cities throughout the world and are designed for the last leg of a journey — from the train or bus to the office.

As they are "dockless", the scooters can be found all over towns at the end of the day.

However, there are clusters of scooters at spots of anticipated high use, including bus stops and Fringe venues.

Mr Price said a team of drivers known as "juicers" were responsible for collecting the e-scooters.

"They're people who can go around and pick up scooters with their car and they can also get paid to do so and charge them at home every night," he said.

Mr Price said the company would work with the State Government to implement longer trials in the coming weeks.
