Road safety experts say the number of road accidents in Lincolnshire has dropped since the introduction of a rural safe-driving campaign.
The Red Route scheme started 18 months ago with signs at 12 well-known accident hotspots in the county.
The scheme has resulted in a 25% reduction in the number of serious accidents on county roads.
The police say the new campaign seeks to remind motorists to drive carefully on rural roads.
Richard Greener, Lincolnshire Road Safety Partnership development manager, said: "Rural roads are a particular cause for concern in this county.
"Eighty-eight people were killed and 274 were seriously injured on such roads in Lincolnshire last year."
