The Christmas carnage on the roads in Northern Ireland has led to a fresh appeal for caution from motorists.
Inspector Rosemary Leech from the PSNI's Road Policing Development branch urged all those using the roads to be extra careful over the holidays.
She said: "Our message to people is to take more care, slow down, don't drink and drive, wear your seatbelt at all times and be aware of other road users."
Insp Leech also reminded motorists that speeding is a significant factor in many collisions, prompting her to urge motorists to slow down.
She said: "Up to 25-30% of fatal collisions will have an element of speed. It will not be speed in isolation, it will be combined with other factors, but common-sense tells you that if you're going to be involved in a collision and you're travelling at a high speed the impact is going to be worse."
Insp Leech said figures showed a year-on-year decrease in the number of people being killed or seriously injured on Ulster's roads.
She said care should be taken over the festive period when there was often more traffic on the roads due to people visiting friends and relatives and going shopping.
