Drivers eating cereal and having a shave are among 151 motorists to be stopped by two police forces in one week for being distracted behind the wheel.
Hampshire and Thames Valley police forces carried out the joint crackdown on distracted drivers on main roads and motorways in the region including the M3, M4, M40, M27 and A34 during a five-day period last week.
Of those stopped, 137 were caught for using their mobile phone and others were stopped for reading books or eating.
One van driver was stopped on the M27 for eating his breakfast cereal while driving and a HGV driver was caught shaving on the M4.
Other offences included 25 motorists stopped for excess speed and eight for careless driving as well as others for no insurance, no tax and insecure loads.
The officers used a HGV tractor unit to view the behaviour of the drivers of HGVs and other vehicles.
A Hampshire police spokesman said: "Many of those stopped for using their mobile phones were found holding their devices below the steering wheel, with the drivers looking at the screen instead of the road ahead."
Sergeant Paul Diamond said "It is disappointing to see so many people still using mobile phones while they are driving.
"If a driver's attention is on their mobile phone, it is not on the road and this can be potentially fatal.
"Sadly, we have seen many examples over the last 12 months of lives lost unnecessarily because a driver has not had their full attention on the road.
"That is why identifying distracted drivers is a priority for the Roads Policing Unit across Hampshire and Thames Valley and we will continue to target drivers who choose to disregard the safety of others."
