Drivers fined for taking photos of Haverhill lorry crash
PC Wayne Sturman, of the force's Commercial Vehicle Unit, said drivers caught would be fined GBP200 and issued six penalty points.
"It was incredibly disappointing to see so many people flouting the law in front of our eyes by taking photos or videos of the collision scene," he said.
"Two of the 18 people were themselves behind the wheel of an HGV, which was particularly thoughtless and negligent of them as professional drivers - especially given the collision involved a lorry and the damage they can cause.
"Using a phone whilst driving is dangerous - even more so in this scenario where drivers are likely to be further distracted by the collision scene."
Officers said they also witnessed a van drive the wrong way around the roundabout and down a stretch of grass to avoid the closure.
A police spokesperson said this person could expect to receive a notice of intended prosecution in the post for driving without due care and attention.
