Hydroplaning

If water has accumulated to a certain depth on the road surface, there is a danger of hydroplaning occurring, even if:
• you drive at low speeds.
• the tires have adequate tread depth.

For this reason, in the event of heavy rain or in conditions in which hydroplaning can occur you must drive in the following manner:
• reduce your speed
• avoid ruts
• brake carefully
