Driving offences that result in death should lead to lengthy custodial sentences, according to a report by the Sentencing Guidelines Council.The body stated drivers ought to go to jail for offences involving prolonged, persistent and deliberate bad driving, alcohol consumption and drug use. In addition, motorists causing accidents because they are distracted by reading or composing text messages on mobile phones should serve up to seven years in prison, the group claims.Chairman of the council Lord Phillips of Worth Matravers said: "Sentencing in cases where death results from the misuse of a car on the road are among the most difficult for judges and magistrates."He added while death on Britain's roads is the greatest harm anyone can inflict, reasons for doing so can result from consistent misuse of a vehicle to "a terrible moment of inattention." Earlier this month, figures released by Accident Exchange showed 700,000 drivers a year run into or scrape parked cars, with vehicles left on the street most commonly hit.
