Pembrokeshire's roads policing unit (RPU) and armed response unit (ARU) have vowed to continue targeting those who flout the law, following a successful 2009.
Last year the RPU caught 141 more people driving whilst using a mobile phone than the previous year, issued 30 more speeding fines and took 385 vehicles off the road for not having the correct documentation.
Pembrokeshire division increased the number of breath tests it carried out by over 3,000 but 65 less drivers were caught driving while over the legal alcohol limit.
Inspector Andy Phillips said: "Hopefully the message about drink driving is finally getting through.
"However we have seen an increase in other offences such as driving without the correct documents.
"This can result in your car being seized from it so we urge people to obey by all the laws of the road or there maybe expensive consequences."
The unit, along with the ARU, also detected 181 crimes, arrested 165 people for drug offences and issued 58 cannabis warnings.
Inspector Phillips added: "The RPU and ARU are proactive in their approach and aim to deny criminals use of the roads and keep the roads of the county safe."
