More drivers are using hand-held mobile phones than before tougher penalties were introduced two years ago, the Transport Research Laboratory has said.

ACCIDENTS THROUGH MOBILE PHONE USE
I was involved in an accident on the way to work. A driver who was having a mobile phone conversation ran in the back of my car at 60 miles an hour. The force of the crash caused my car to domino into the car in front. I got whiplash and the rear of my car was smashed up. A ban and custodial sentence is the only way to get through to some stupid people in our society that using a phone whilst driving is a lethal weapon which may seriously injure and worse still could kill!

I nearly had an accident 10 years ago while using hand held phone. Since then I have never used one in the car. All cars fitted with a blocking device is the only solution, I am not a traffic policeman but I can detect anyone using a phone just by their driving characteristics.

In the last few weeks I have seen at least nine near-misses where a driver using a hand-held mobile has almost collided with another road user or pedestrian. The fact is there is no excuse for using a mobile whilst driving; we are all taught to have both eyes on the road and to have two hand to operate the vehicle; also a Bluetooth headset only costs approx. £25.00.

EXTREME EXAMPLES OF BAD DRIVING
I have even observed a school bus driver using a mobile, I regret not ringing his company and informing them.
M Bugg, Beeston, Nottinghamshire
I ride a motorbike and have had several near misses where the driver has been on the phone. I have seen one person, a truck driver, on the phone and eating a sandwhich at the same time - they cannot be in control of the vehicle.
Peter, Wareham, Dorset
I drive about 25,000 miles each year commuting to work and travelling on business. There have been numerous occasions when I have had to take avoiding action to avoid being hit by either a ''white van'' or a lorry. Upon overtaking the offending vehicle I have found that they are almost invariably holding a mobile phone to their ear. I think the fines need to be made considerably higher or some means of making mobile phones ineffective in vehicles.

Travelling on the M1 from Luton to Watford every day, I see too many people on mobile phones. It is a scary observation as their driving is clearly not up to the standard you should expect. Let's show more TV adverts with the consequences of using a mobile and how it can kill people. Enforce a 12 months ban on driving and a £1000 fine. £60 and three points is not enough to stop anybody.
Jillian Still, Hitchin, Herts
Using a Mobile phone when driving should warrant at least a fine and 3 points on your licence, for a first offence, a second offence within 5 years should warrant a 12 months driving ban.
Michael Connell, Bury
Being a serving police officer I am never surprised by findings such as these. When I issue a penalty for this offence I am often faced with the 'haven't you got anything better to do' response. People do not take the matter anywhere near seriously enough.
We should stop the current obsession with speed cameras and get back to proper traffic policing, using both marked and unmarked cars. I drive about 25,000 miles a year and on the rare occasions I have to take evasive action, it is usually a mobile phone user.
I see at least one person every day on my drive to work with their mobile up to their ear. Many people send texts while they drive, with their eyes down in their laps! Somehow, they think no-one can tell they're doing this.
Stuart Richings, Cirencester, Gloucestershire
On-the-spot confiscation and destruction of the SIM card would probably concentrate the mind wonderfully.
I am a school governor and I see mums driving to my school with the children not wearing seat belts, ignoring parking restrictions and chatting on their mobiles. It's about time laws were enforced in this country.

HANDS FREE COMMENTS
Everyone has a different capacity to multi-task. Whilst I don't think anyone should be using a (non-hands free) phone whilst driving, some people are better at doing other things when driving than others. People should drive according to their abilities.
Hands free means your hands are free to put on the wheel so you are in total control of the car. To say hands free conversations are still dangerous is mad. Are we eventually going to be stopped from talking to any passengers in the car as well?
Dez, Houghton Le Spring
I don't use a hand-held phone but do use a hands free. Should we ban that too? Along with shouting at any children in the back seats, singing along to the radio, arguing, tuning the radio, changing tapes, basically anything that distracts us from the task at hand.
