Vehicles in Jersey drive on the left side of the road. The island has a default speed limit of 40 miles per hour (64&nbsp;km/h) with slower limits on certain stretches of road, such as 20/30&nbsp;mph (32/48&nbsp;km/h) in built up areas and 15&nbsp;mph (24&nbsp;km/h) on roads designated as ''green lanes''.<ref>{{Cite web|title=Speed limits and speeding|url=http://jersey.police.uk/be-safe/road-safety/speed-limits-and-speeding/|access-date=2020-12-10|website=jersey.police.uk}}</ref><ref name=":0">{{cite web |url=https://www.gov.je/SiteCollectionDocuments/Travel%20and%20transport/IDJerseyHighwayCodepdf20090923Clem.pdf |title=Jersey Highway Code |publisher=[[States of Jersey]]}}</ref>

The island is home to longest dual carriageway in the Channel Islands, consisting of [[A2 road (Jersey)|Victoria Avenue (A2)]], and the [[A1 road (Jersey)|Esplanade/Route de la Liberation (A1)]]. Roads in Jersey are often named in French or [[Jèrriais]], except in St Helier, where they are often named in English.

Public highways are state-owned and managed by public highways authorities. Main roads are maintained by the [[Government of Jersey]] and funded through general taxation. By-roads (''chemins vinciaux'') are managed by the relevant parish through a [[Roads Committee]]. [[Roads Inspector]]s are elected to report on roads in their [[vingtaine]].

Roads in Jersey are classified using two systems. The first is the signposted system for classifying main roads, consisting of an "A", "B" and "C" system as used in Great Britain, Northern Ireland and the Isle of Man. These are often signed on directional signs, however some are inaccurate.

The second is a system used privately by the Government of Jersey to classify both main roads and by-roads.<ref>{{cite web |title=ArcGIS |url=https://maps.arcgis.com/home/webmap/viewer.html |website=maps.arcgis.com |access-date=26 May 2023 |language=en }}</ref> The system consists of Class 1, 2 and 3 roads (main roads) and Class 4 roads (by-roads). Class 1 roads include Victoria Avenue.

A [[Visite du Branchage]] is an inspection of roads to ensure property owners have complied with the laws against vegetation encroaching on the highway.

==== History ====
Until the 19th century, Jersey's highway system comprised narrow and muddy tracks connecting homes and fields to the churches, mills and beaches. Around the turn of the 18th century, the number of roads are described as "[holding] no Proportion with the Bigness [of the island]". The sides of the road, unlike in England had "great Bulwarks of Earth ... from 6 to 8, and sometimes 10 Foot high". At the time there were three types of road: {{Lang|fr|Les Chemins du Roi}}, which, including the banks, were 16 feet wide; {{Lang|fr|Les Chemins de 8 pieds}}, which were 12 feet wide; and {{Lang|fr|Les Chemins de 4 pieds}}, which served only carriages on horseback.<ref>{{Cite book |last=Falle |first=Philip |url=https://quod.lib.umich.edu/e/eebo/A40814.0001.001/1:15.1?rgn=div2;view=fulltext |title=An account of the Isle of Jersey, the greatest of those islands that are now the only reminder of the English dominions in France with a new and accurate map of the island |publisher= |year=1694 |isbn= |location=London |pages=64–66}}</ref>

In the early 19th century, the military roads were constructed (on occasion at gunpoint in the face of opposition from landowners) by the governor, [[George Don (British Army officer)|General George Don]], to link coastal fortifications with St. Helier harbour. These had an unexpected effect on agriculture once peace restored reliable trade links. Farmers in previously isolated valleys were able to swiftly transport crops grown in the island's [[microclimate]] to waiting ships and then on to the markets of London and Paris ahead of the competition. In conjunction with the later introduction of [[steamship]]s and the development of the French and British [[railway]] systems, Jersey's agriculture was no longer as isolated as before.
