The latest Department for Transport figures show that 30 more people died and 1,760 more were badly hurt on UK roads in the 12 months up to June 2016, compared with the previous year.
A total of 24,620 people were killed and seriously injured, a rise of 3% compared to 22,830 in 2015. Fatalities for the year rose 2% to 1,800 compared with 1,770 in the corresponding 12 months for 2015.
The TTC Group provides training and education to more than 330,000 motorists each year through workshops for businesses and also to individuals as part of the National Driver Offender Retraining Scheme after minor road traffic offences and collisions.
"Sadly people are making fatal mistakes on the road leading to unnecessary deaths and serious injuries which could and should be avoided if we all took more care on the roads.
"Driver error is regarded as a key factor which causes these collisions and drivers must take responsibility for their own safety, their passengers and all other road users to ensure we reduce these needless deaths and injuries," said Alan Prosser, TTC director.
