ST. PETERSBURG, Fla., Nov. 22, 2016 /PRNewswire/ -- From heavy snow to icy roads, winter travel is not without its problems. Leading travel insurance comparison site Squaremouth asked providers to share the most common misconceptions about winter travel coverage and what travelers should know when searching for a policy for their winter trip. [ WATCH VIDEO] I Can Wait to See if the Weather Looks Bad Before BuyingIf the forecast is looking bleak for your upcoming trip, it may already be too late to buy a policy. Travel insurance is designed to cover unforeseen events. Once a winter storm is named, it is considered foreseen, and new policies will no longer provide coverage for that storm. "It's important to understand that benefits are not provided if a snowstorm or blizzard is identified and named on or before the start date of your coverage," said Jim Krampen, co-founder of travel insurance provider Seven Corners. "You need to buy the coverage before a storm develops." I'm Automatically Covered if My Flight is DelayedTravel delays are the most common weather-related claim during the winter months, but it is important to understand your policy's minimum delay requirements. Travel Delay or Missed Connection benefits are typically triggered after 3-12 hours, depending on the policy. These benefits can cover extra expenses during a delay, additional transportation to catch up to your trip, and lost expenses from the missed portion of your trip. However, they are typically limited to $100-$1,500 per person and often have a daily limit. Trip Cancellation benefits can also kick in if bad weather significantly delays your flight — typically by at least 12-48 consecutive hours. "Policyholders often make the mistake of assuming that any delay on their airline flight makes them eligible for coverage," said APRIL Travel Protection CEO Jason Schreier. "One of the most common reason claims are denied is because the minimum number of hours haven't passed in order for coverage to apply." I'm Covered For Any Bad Weather That Affects My TripMost policies include coverage for flight delays due to inclement weather, but winter weather can affect travel in other ways. Heavy snow or icy roads could make it difficult to get to the airport, but many policies do not provide coverage for poor road conditions. "Travelers often mistakenly believe they are automatically covered if there is any kind of bad weather," said RoamRight Senior Vice President of Travel Linda Fallon. "In truth, travel insurance policies have very specific language and criteria that must be met for coverage." Some travel insurance policies include Travel Delay coverage if roads are closed due to bad weather, but few travel insurance policies will cover you to cancel your trip altogether for this reason.
