Deerfield has it's own fairly comprehensive bicycle laws on the books. Some things to keep in mind are:
- White headlight AND white front reflector as well as a red rear reflector are required
- Persons under 16 are required to use helmets
- Kids under 12 must use the sidewalks along Deerfield Road or Waukegan Road or County Line (Lake-Cook) Road
- In business districts bicycles may be ridden on sidewalks
- Riders must ride single file
- No cycling under the influence of drugs or alcohol
- No riding no-handed
