City rangers recently blitzed trouble areas, including Port Kennedy and Golden Bay, issuing 16 infringements last month for illegal off-road activity.
With a likely surge in activity over the Easter long weekend, rangers will continue to patrol reserves, beaches and bushland.
Mayor Barry Sammels said anyone caught using a trail bike or vehicle illegally would face harsh penalties and even prosecution and would not get a warning.
‘The biggest danger of illegal off-road driving is the risk of accidents between four-wheel drives and motorbike riders,’ he said.
‘Rangers are not giving warnings at all for illegal off- road activity. The message is if you are caught, you will be fined.
‘It is absolutely not acceptable for people and children to be put in danger as a result of four-wheel drives or other vehicles illegally accessing and driving on a beach.’
Cr Sammels said residents should not approach illegal off-road drivers or riders but report them and any details to rangers on 9528 0333.
