A motorist who chased a man with a three foot pole during a "road rage" incident on the Lincoln bypass was jailed for six months.
Craig Burrell, 37, admitted arming himself with the weapon after pulling infront of a transit van on the A46 between the Bentley Hotel and Doddington Road roundabouts.
Lincoln Crown Court heard there was a history of problems between Burrell and his victim, John Shepherd, who were both from Long Bennington.
Andrew Scott, prosecuting, told the court Mr Shepherd was left with a cut hand after Burrell used his fist to smash the window of his van.
When Mr Shepherd tried to escape by climbing through the back of his van Burrell returned to his own vehicle and armed himself with a "three foot wooden stick", Mr Scott said.
Burrell then chased Mr Shepherd around his transit van several times. Mr Scott added: "Mr Shepherd jumped into a strangers car and asked to be locked in."
The court heard Mr Shepherd suffered a loss of £600 through damage to his van and time off work.
In mitigation the court was told Burrell had now moved away from Long Bennington to Lincoln, and there had been no further problems with Mr Shepherd.
Burrell, of Fairfax Street, Lincoln, admitted a charge of affray. Passing sentence Recorder Adrienne Lucking told Burrell the incident took place in broad daylight and she had no choice but to send him to jail.
