Drivers had been warned they could be fined up to £300 and slapped with as many as 11 points on their driving licence for breaking major Highway Code rules this month.
The warning comes as thousands of drivers prepare to hit the roads as students return to university following the end of summer.
Students will pack their vehicles fully with belongings and travel to campuses across the UK, with many travelling for the first time.
Safety experts have now warned that moving into halls could cause serious road risks due to drivers overfilling cars and blocking views from mirrors.

Drivers can be fined £300 for travelling with blocked views in their vehicle

Under Rule 161 of the Highway Code, drivers are required to keep mirrors clear and maintain a rear view of the road at all times while behind the wheel.
The rule states: "All mirrors should be used effectively throughout your journey. You should use your mirrors frequently so that you always know what is behind and to each side of you.
"Use them in good time before you signal or change direction or speed. Be aware that mirrors do not cover all areas, and there will be blind spots. You will need to look around and check."
Research revealed that almost a third of students took a car with them to university, with Bryn Brooker, the company's head of road safety, explaining that while bringing a car offered freedom, it also carried pitfalls that could not be ignored.

"Blocking the rear window wasn't technically illegal, but if overpacking obstructed the driver's front view, affected handling or pushed the car over its weight limit, it became a punishable offence," he said.
In the UK, drivers can be fined up to £300 and receive as many as 11 penalty points. However, new drivers could risk losing their licence for having an obstructed view.
Drivers have been hit with fines for unloading in resident-only bays, on double yellow lines or blocking pavements and driveways, which all breach the Highway Code.

Mr Brooker added: "Heading to university often means packing your car full of essentials, but overloading can affect handling and make driving harder, especially if you're not used to it.
"While blocking the rear view isn't illegal, exceeding weight limits, affecting control, or obstructing the front view could land you with fines."
But Mr Brooker also raised another alarming trend surrounding spikes of drink-driving during the return to university period.

| GETTYReports found that nearly half (49 per cent) of 16-34-year-olds have been driven by someone who may have been over the legal alcohol limit, with 43 per cent of Gen Z and 52 per cent of Millennials admitting to having taken this risk.
The alcohol limit in England, Wales and Northern Ireland is 80mg of alcohol in 100ml of blood, with drivers caught above this threshold facing severe consequences, including a three-month prison sentence as well as a £2,500 fine.
Mr Brooker added: "With Freshers' Week and the start of term bringing plenty of social events, it's important to plan ahead for safe travel.
"Whether that means booking a taxi, arranging a lift with someone you trust, or walking home with friends, making a safe choice ensures you enjoy the night without putting yourself or others at risk."
