Note
The gazette entry is written as a complicated delete and substitute process for each clause making it difficult to read, unlike previous gazetted regulations which deleted all and replaced the entire rule 51. The information above is as it appears in the amended Road Traffic (Miscellaneous) Regulations 2014 to make it easier to read & remained unchanged in 2019.
