Jersey Safe Roads

Safe Speed

Maintaining safe speeds on Jersey’s roads is essential for reducing collisions and their severity as part of the broader Safe System Approach. By managing speeds effectively, we contribute to creating a safer environment for all road users, including pedestrians, cyclists, drivers, and passengers.

As Jersey’s roads are uniquely characterised by their mixed usage and distinct design, our speed management strategies must balance accessibility with safety to protect all road users effectively.

On this page, you will find information about Jersey’s speed limit framework, practical insights into speed compliance and penalties for speeding, and findings from speed studies exploring the connection between vehicle speed and injury severity. 

Setting Appropriate Speed Limits

Managing traffic speeds will help make Jersey’s roads safer and more inclusive for everyone, particularly vulnerable road users like pedestrians and cyclists. Encouraging safer speeds will be especially important around schools, residential areas, and popular tourist destinations.

Speed limits will be set based on a clear framework designed to ensure consistency and fairness across the Island. A review of all speed limits is currently underway to align them with this framework. Details are outlined below:

40MPH

The all-Island maximum speed limit is 40mph, or 30mph for vehicles over 3.5T or towing a trailer.

30MPH

All roads in the urban area should be subject to a 30mph speed limit, with extensions into rural areas where appropriate.

20MPH – Village

The all-Island maximum speed limit is 40mph, or 30mph for vehicles over 3.5T or towing a trailer.

20MPH – Residential Area

Residential areas that are not “through routes”, where pedestrian and cycle movements are likely to be high should be 20mph.

20MPH – Tourist Bays

Tourist bays where pedestrian and cycle movements are likely to be high should be 20mph.

20MPH – School Zones

Part-time 20mph zones may be signed around schools, at times when children are present.

15MPH – Green Lanes

Green Lanes have a 15mph speed limit. Motorised vehicles should give priority to pedestrians, cyclists, and horses at all times.

Please note that where the framework indicates a 40 or 30mph speed limit, a lower speed limit may be applied for road safety reasons.

Speed Compliance

The States of Jersey Police actively enforce speed limits using manual speed detection equipment. These checks are frequently conducted in areas identified as speeding hotspots. Additionally, other locations may be monitored in response to community concerns about speeding vehicles.

Speed Indicator Device

To raise awareness of speed limits, portable speed indicator devices are strategically deployed across the Island. These devices display the speed of approaching vehicles along with a visual prompt: a sad face for speeds exceeding the limit and a happy face for speeds within the limit. Their primary purpose is to encourage compliance with speed limits and to increase driver awareness. Often, driving can become an automatic act, and motorists may not realise they are exceeding the speed limit. These devices serve as a gentle reminder to remain attentive to their speed.

Penalties for Speeding

If you are caught speeding, the consequences will depend on the severity of the offense:

If found guilty, penalties can include: 

Public Awareness

There is a common misunderstanding about speed among motorists. Many believe that speeding is not an issue as long as they drive carefully. However, unforeseen circumstances can arise while driving, and to minimise the potential negative effects, it is crucial to adhere to the speed limit and adjust your speed according to the environment, including weather, road, and lighting conditions.

Speed Studies 

The research below emphasises the essential role of speed management in enhancing road safety. Numerous studies have examined the connection between vehicle speed and the severity of injuries. Generally, these studies conclude that higher speeds lead to more severe injuries.

1mph change in speed = 5% change in collision rate

Pedestrian Fatality Rates:
Hit at 20MPH = 1%
Hit at 30MPH = 20%
Hit at 40MPH = 31%

1kph change in speed = 6% change in injury collisions

The figures, based on collisions with at least one contributing factor recorded, show that more than half (56%) of fatal collisions in 2023 had at least one speed related factor assigned.
