HRS §291C-102
Driving faster or slower than the speed limit is illegal
Read the official text at capitol.hawaii.gov ↗This law says you cannot drive faster than the maximum speed limit or slower than the minimum speed limit set by county rules or official signs. If you go more than 10 miles per hour over the limit, you must pay an extra $10 fee. This fee goes to a special fund for brain and spinal injuries.
