Cornwall Council is cracking down on parents and guardians who park illegally outside schools.
This includes parking or waiting on yellow keep clear and zig zags areas. Doing so can attract a £70 fine.
The council says the move is in response to an increase in the number of schools reporting problems.
The Highway Code already forbids parking, waiting or dropping off on yellow zig zags outside schools, but the council says people manage to get off using loopholes like missing signage as an excuse.
Number plate recognition systems could also be introduced if the problem persists at schools.
