Metric speed limits for trams in the UK: www.londontransport.co.uk/trams/passengerhelp/safety/safety_index_trams.shtm l (beware of line wrap)
Dual metric/imperial signs for height and width. But not length. www.highwaycode.gov.uk/signs04.shtml Note also the overhead electrical cable sign. The example gives an imperial only height on the plate. It is not clear if this can also be dual metric/imperial. www.highwaycode.gov.uk/signs05.shtml The rationale given by the government for these dual metric/imperial signs is to permit free movement of goods by commercial vehicles within the EU. -- Terry Simpson Human Factors Consultant [EMAIL PROTECTED] www.connected-systems.com Phone: +44 7850 511794
