Renfrew OPP is reminding drivers to slow down after four people have been charged with stunt driving over the past month.
All four were caught driving 50 kilometers an hour over the posted speed limit on Highway 17.
Two women aged 21 and 42 years old and two men aged 21 and 39 have been issued summons to appear in court later this month.
The police want to remind drivers that speeding at such high rates is very dangerous and will result in having your license suspended and car impounded.
