About 1,000 people attended a rave at Twyford Wood near Bourne in Lincolnshire on 23 May.
Police carried out an operation to close it down, which led to 21 officers and a dog being injured.
Chelsea Harvey, 21, from Norfolk, admitted dangerous driving and was jailed for 12 months.
Harvey, of Ashley Walk, Dereham, drove her Peugeot 206 about 350 metres (1,148ft) at speeds of up to 30mph (77km/h) with PC Rob Bentley on the bonnet, Lincoln Crown Court heard.
At one point she was involved in a collision with a camper van, but continued with the officer still clinging on.
PC Bentley suffered "relatively minor physical injuries" but the court heard the psychological damage had had a lasting impact.
James Bide-Thomas, prosecuting, said Harvey, who had two female friends in her car, had been told to stop by PC Bentley, but instead had "jerked forward violently" knocking the officer off his feet and leaving him "spread-eagled" on the bonnet.
Judge Michael Heath, passing sentence on Wednesday, told her: "If you drive as you did with a police officer on your bonnet for the distance that you did, and at the speed you did, there can only be one sentence that I can impose upon you. That is immediate custody."
Jonathan Straw, defending, said Harvey works in a centre for deaf-blind people run by the charity Sense.
He described her as acting in "blind panic" and added: "She is very sorry for what happened. She didn't intend to hurt anyone. She went out with two friends that day simply to enjoy a party."
Harvey was also disqualified from driving for a year.

He made the statement in a video for the Church of Scotland.
Mr Salmond, who is now the SNP MP for Gordon, also said that he believed all denominations had a key role to play in society.
The Scottish Secular Society said the politician's remark was "controversial and divisive".
But a spokesman for Mr Salmond later clarified that the former first minister had been "talking about faith, not religion".
Mr Salmond, who is the SNP's foreign affairs spokesman at Westminster, was featured in the video alongside the Rev Stuart MacQuarrie, the Church of Scotland's chaplain to the University of Glasgow.
The clergyman had been at Holyrood to deliver the first "time for reflection" of the new parliamentary year.
Mr Salmond recalled that he was a champion for the chamber event, which features religious and humanist speakers.
Speaking during the three-minute video, he said: "I am biased, of course, because I am a Church of Scotland adherent and I prefer people of faith to people of no faith or people who have lost their faith.
"All denominations have a key role to play in society and we are very fortunate in Scotland because we have a tremendous ability, among religions and denominations, to come together and support good causes."
The chairman of the Scottish Secular Society, Spencer Fildes, said he was unhappy with Mr Salmond's comment.
He said: "For Alex Salmond to say he prefers people of faith is a controversial comment to make.
"With one sentence he has separated the religious and none religious, affording special place to the religious in his own world view; preferring one half of the country to the other.
"It's an incredibly ill-thought and divisive comment to make."
Gordon MacRae, chief executive of Humanist Society Scotland, also said he believed Mr Salmond's comments had been "deeply innapropriate".
He added: Non-religious people in Scotland constitute a larger group than any single religious denomination, and non-religious humanist wedding ceremonies are now one of the most popular ways for couples in Scotland to celebrate their love."

The body of Sinead Wooding, 26, was found by joggers near Alwoodley Crags car park in Stairfoot Lane on 14 May.
Vicky Briggs, 25, of Throstle Road, Middleton, appeared at Leeds Magistrates' Court accused of assisting an offender.
She was bailed to appear at Leeds Crown Court on 16 June. Two people have previously been charged with murder.
A 20-year-old has also been charged with assisting an offender.
A woman drove at a police officer manning a road block and carried on for 350 metres with him "spread-eagled" on her bonnet, a court heard.
