markings and signs to Alderney and Sark. Sark does not permit road transport, aside from cycles and farm vehicles. Alderney has some different road markings, but the signs are broadly the same as Guernsey. Overseas territories The Overseas territories have much more autonomy regarding their use of signs and these can vary quite significantly from those used in Great Britain. Akrotiri and Dhekelia Road signs in Akrotiri and Dhekelia, on Cyprus, are controlled by the Ministry of Defence and maintain the same designs as the Republic of Cyprus. Speeds are in kilometres per hour, distances are in kilometres. Some signs are in Turkish as well as English and Greek. Anguilla Anguilla mostly uses the same road signs as the United Kingdom with minor differences. Anguilla's roads occasionally cross large dish drains requiring a vehicle to slow down to cross. Because of this, the territory has its own unique dip sign. Ascension Island Ascension Island mainly uses signs similar to the UK's, but the yellow diagonal signs common to the US are also found on the island. Bermuda Bermuda mostly uses the same style as the United Kingdom, with some exceptions. Speed limit signs are in kilometres per hour and occasionally miles per hour, and all limit signs have this marked. Longer distances are typically in kilometeres, however shorter distances are signed in yards. Height and width sign restrictions are in both imperial units and metric. No entry signs have "NO ENTRY" written in black down the centre as was often used in the UK prior to 1965. Goods vehicles are prohibited by class rather than weight: a list of prohibited vehicle classes will usually accompany a generic "no lorries" sign. Bermuda still uses the Z-bend sign, phased out in the UK since 1975. British Indian Ocean Territory The British Indian Ocean Territory's road signs are modelled on those of the US's Manual on Uniform Traffic Control Devices. Cayman Islands The road signs of the Cayman Islands are similar to the UK's; the only main difference is some signs have allowable alternatives from the US's Manual on Uniform Traffic Control Devices, mainly for parking restriction signs. The warning sign for dead ends is one of the only signs to follow the US standard in the Road Code, although other US-influenced signs are listed for use near schools. In practice, the Transport typeface is not used and signs are written in all
