Dangerous driving is a contravention of Section 2 of The Road Traffic Act. 

The penalty for this offence is a maximum prison sentence of two years in solemn proceedings, and six months in summary proceedings with obligatory endorsement, and disqualification for a minimum period of 12 months. Any person convicted of this offence after disqualification must resit and pass the extended driving test before his licence is returned. 

To prove the charge the prosecution must prove the driving was of a standard than would not be expected of a careful and competent driver. It also has to be demonstrated that it would be obvious to a careful driver that the standard of driving would be considered as dangerous.
