If convicted the authorities could impose the maximum penalty for each illegal immigrant found, which would mean the driver's fine surpassing the current record of £50,000.
The chase involving eight police cars started when the driver, disembarking from a cross-Channel ferry at Dover, ignored immigration officers' requests to stop.
Officers all over Kent were alerted to the chase involving the seven-and-a-half tonne lorry, which lasted for more than an hour.
The driver of the lorry could face a £2,000 fine for each illegal immigrant under tough new laws recently introduced by the Home Office to crack down on human trafficking.

Hot pursuit
During the chase, the driver managed to foil police attempts to burst the lorry's tyres with a "stinger" device - spikes thrown across the road.
The vehicle was pursued up the M20 towards London before it turned onto the A228 at Cuxton and was forced into a ditch by two police cars that had blocked the road ahead.
Thirty men of Asian appearance were found in darkness inside.
A police officer is in hospital with a back injury and two police cars were damaged when the lorry collided with them. The A228 was closed for 40 minutes.
A police spokesman said: "The chase lasted for an hour and the lorry reached speeds of up to 50mph.
"The 30 men were taken into custody and have now been handed over to immigration officials."
Police said they were questioning a man on Saturday evening, after he received treatment for a suspected broken arm.
In June, shocked customs officers at Dover discovered the bodies of 58 Chinese people - and two survivors - in a sealed lorry container at the Kent port.
