DentroTest · Accepted Answer

The vertical information sign S-16 indicates the location of an emergency braking zone. This space is built off the roadway, usually with materials such as gravel or sand, on sections with steep downhill slopes, to allow a vehicle to stop safely in case of a failure of the braking system. It must not be confused with a rest area (signed with sign S-123) or a dead-end street (sign S-15a).
