These plates are used on limousines and for-hire cars (but not taxis).
The ‘Livery’ type started in 1910 and was used on vehicles which transported people for a charge.
Livery plates were issued from 1910 to 1915. They were the reverse colors of passenger plates with an ‘L’ suffix. 1916 was skipped because ‘Commercial’ vehicle plates were used on individual-fare for-hire vehicles. From 1917 to 1920 they used ‘Public Service’ plates, with a ‘PS’- prefix (this type was shared with buses). In 1921 ‘Public Service’ became ‘Omnibus’, with an ‘O’ prefix. Livery returned in 1932 and has been in use since.
In the late 1980s, the format changed from all-numeric to one having an ‘L’ prefix and suffix – similar to Interstate (Z) and Taxi (T) plates. The standard configuration at this time was L1234L, although lower numbers appear in L1L, L12L, and L123L formats. In March, 2016, a 7-digit format was introduced starting at L00000L (number verified on the road).
