Are there any exemptions from the ULEZ charge?

Several exemptions exist, including vehicles with a disabled passenger tax class or disabled driver tax class, military vehicles, historic vehicles manufactured before 1 January 1973, and certain specialist vehicles. 

Blue Badge holders do not automatically receive exemption - only vehicles with the specific disabled tax class qualify. Residents living within the original central ULEZ zone had a sunset period for exemptions, but these have now expired. Most drivers need a ULEZ compliant vehicle to avoid charges.
