Gardai had to be quick on Friday - after stopping a driver who was speeding at nearly 200kph on one of the busiest roads in the country.
The M7 connects Dublin to Limerick via busy towns like Naas, Newbridge, Portlaoise, Nenagh and others.
It's usually quite busy, particularly on weekends, and it was on Friday afternoon that officers in the midlands nabbed the motorist for going 50kph over the limit.
