On weekdays from 7 am to 8 pm and on Sundays and public holidays from 8 am to 8 pm, keep pavements clear, or grit them in icy conditions, to secure pedestrian traffic.
Pavements narrower than 1.50 m fully, otherwise at least 1.50 m wide; shared cycle/foot paths narrower than 2.00 m fully, otherwise at least 2.00 m wide. Where there is no pavement, strips at least 1.00 m wide beside or at the outermost edge of the carriageway; in traffic-calmed areas and pedestrian zones, strips at least 1.00 m wide and accesses at least 0.80 m wide.
Harmful chemicals or salt only where unavoidable to establish traffic safety; sand or other abrasive materials as a rule. Tree pits and planted areas must not be gritted with sand, and salty snow must not be stored on them.
Breaches can be punished with a fine of up to €5,000.
