Seven cars leave same stretch of road in two days
In a Facebook post, the police team said the section of road was "notorious" and had seen "hundreds of collisions over the years".
The post said: "Heavy rainfall after hot weather is the most dangerous time and we take this seriously to prevent loss of life."
Steven Carter, a councillor for Melton Borough Council, said seeing vehicles in the ditch alongside the A6006 carriageway was a common sight in Shoby.
"I used to go down that road every day to work and I used to see a car in there, or a van - I've even seen a lorry in there - every other day," he said.
The independent councillor added: "I don't think there's enough signage there to be honest.
"It's a sharp bend.
Someone's going to end up getting killed there."
A county council spokesperson said: "There are a number of permanent warning signs in place in Shoby - including vehicle activated signs, chevron boards, bend warning signs and slippery road signs - and we're assessing these following the concerns.
"Heavy rainfall after dry spells can affect all road surfaces and we'd always encourage motorists to adapt their driving to the conditions."
