88 Chapter 6 — Sharing the Road Recreational Vehicles and Trailers When you approach a vehicle towing a trailer: Motorcycles and Mopeds Be especially watchful for motorcycles and mopeds while turning or changing  lanes at intersections or entering the road from a driveway. Mopeds and  motorcycles are difficult to see, and can be entirely hidden by your blind spots.  In many left-turn situations it is even more difficult to see a motorcycle or  moped. Look out for motorcycles and mopeds, as well as other vehicles, before  you turn, change lanes or proceed to move. Drivers share the road with motorcycles and mopeds, and they must be  especially careful to look for them and to observe  these precautions : Towing a trailer or boat requires special skill, as well as consideration on the part  of each driver. 20 feet in front of the cab, on either side of the tractor-trailer, particularly  alongside the cab, and up to 200 feet in the rear (see diagram). Motorists lingering in the NO-ZONES hamper the trucker’s ability to take  evasive action to avoid a dangerous situation. An excellent rule of thumb for  motorists sharing the road with a tractor-trailer is,  “if you can’t see the truck  driver in his side-view mirror, he can’t see you.” • Most recreational vehicles, including motor homes, campers and travel  trailers, are longer, higher and wider than passenger cars. • Recreational vehicles and trailers accelerate and stop more slowly than cars  and require more room for turning. • Visibility is a major problem with recreational vehicles. Remember, that the  closer you are as you approach a recreational vehicle, the more it will block  your field of vision. • Drivers of recreational vehicles can lose sight of you because their blind spots  are much larger than those of cars. •  Watch for any sway or possible hazards, such as crosswinds or slippery curves; •  Be aware that sudden braking might cause the trailer to jackknife; and •  Use extreme caution while passing a trailer and the towing vehicle — it  may take you a half mile of clear roadway to safely pass. • Give the motorcyclist or moped rider the same right of way consideration as  you would for the driver of any other vehicle; • Motorcycles are entitled to the full width of their lane. To pass a motorcycle,  you must change lanes and pass in the same manner as you would for a larger  motor vehicle; • A moped should travel using the right side of the lane. To pass a moped, you  must stay at least two feet to the left; and • You must leave any cyclist enough room when you pass so your vehicle’s  windstream cannot cause the rider to lose control.
