Correct!
Your chances depend on your ability to react quickly and properly.

Idaho riders add a motorcycle (M) endorsement to a Class A, B, C or D license after passing the motorcycle knowledge test and a skills test with a third-party examiner. Knowledge and skills test results count for one year.
Riders under 21 must complete an approved rider training course, such as Idaho STAR’s. For anyone, a passing STAR or MSF course can replace the skills test if the endorsement is added within two years of the course.
After the knowledge test you can buy a motorcycle instruction permit, valid one year: daylight riding only, no freeways or highways and no passengers, and permit holders under 18 wear a helmet.
Idaho riders keep at least a three-second following distance in normal conditions, and lane filtering and lane splitting are not legal in the state. Idaho Motorcycle Rider’s Handbook p. 40–45

Everyone under 18 must wear a DOT-compliant helmet on a motorcycle or ATV, on or off the highway. The handbook strongly recommends a helmet, eye protection and protective gear for every rider. p. 19
No. Carrying a child passenger in front of you is not legal in Idaho; a child rides immediately behind you, on a proper passenger seat with passenger footrests. p. 71
No. Lane filtering (moving through stopped or slow traffic) and lane splitting (weaving between moving lanes) are not legal in Idaho. p. 45
Only after a complete stop and waiting one full signal cycle at a signal that fails to detect your motorcycle; then you may proceed with caution. Signals that can detect you, or that don’t use detection, must still be obeyed. p. 51

In Idaho a motor-driven cycle has a motor of 5 brake horsepower or less as manufactured (or an electric motor under 3,729 watts), meets federal safety standards and isn't a moped; it must be titled, and its rider needs a motorcycle endorsement.
In Idaho, a motorcycle, motor-driven cycle or motor scooter with regular highway registration and plates may use all highways, including state, U.S. and interstate highways (except roads requiring an OHV sticker); each needs a title, a driver's license, a motorcycle endorsement and insurance.
Compared with a car, a motorcycle reacts faster to the rider's input and is more sensitive to road surfaces and wind; it is harder to see because of its narrow profile, fewer and smaller lights and lower contrast, and its rider is less protected.
Crashes happen most among untrained or beginner riders; head injuries are as severe as neck injuries and more common, and they make up a majority of serious and fatal injuries to motorcyclists.
Rider training gives the best success in mastering control, because you learn and practice the skills in a safe environment; it covers basic control as well as mental strategies and hazard avoidance, and is worth taking even if you have ridden before.
Sit far enough forward that your arms are slightly bent on the handgrips, so you can press the bars without stretching.
Idaho's handbook teaches SIPDE, a mental strategy taught in many rider courses: Scan, Identify, Predict, Decide and Execute; in the Scan step you search aggressively ahead, behind and to the sides to spot problems before they become critical.
Other road users, such as vehicles, bicyclists, pedestrians and animals, may violate your right-of-way, block your view, crash into you or simply distract you; be especially alert where visibility is limited, since visually busy surroundings can hide your motorcycle.
However careful you are, you may end up in a dangerous situation, and getting out safely depends on reacting quickly and properly; crashes often happen because the rider wasn't scanning far enough ahead, wasn't prepared, or lacked obstacle-avoidance skills.
A front-wheel skid comes from applying too much front brake and immediately costs steering control and balance; release the front brake at once and completely, then reapply it smoothly, because not releasing it right away can cause a crash. ABS is designed to prevent such skids.
Before riding with a passenger or heavy load, practice away from traffic, adjust the suspension if you can, consider adding a few pounds of tire pressure, and adjust the mirrors with both of you seated, since the motorcycle's angle changes.
When leaving the highway, give clear signals that you'll slow and change direction, tapping your brakes to flash the brake light before slowing, and check your mirror and make a head check first, since drivers behind may not expect you to slow.
ITD doesn't publish the number of questions or the passing score. Our practice exam uses 25 questions with 20 to pass (80%). The test is given at county driver's license offices.

You wait three days before retesting and pay the test fee again. Passed knowledge and skills results stay valid for up to one year. Idaho Motorcycle Rider’s Handbook p. 17
You need 20 of the 25 questions right (80%). Always confirm the current test with the Idaho Transportation Department, Division of Motor Vehicles. Compare every state
You can miss up to 5 of the 25 questions: you need 20 right (80%) to pass.
Yes if you are under 21: Idaho requires an approved rider training course before the endorsement. For everyone else it is recommended, and an Idaho STAR or MSF course can waive the skills test if you add the endorsement within two years of finishing it.
Practice on public roads for up to a year after passing the knowledge test, but only in daylight, never on freeways or highways, and never with a passenger. Permit riders under 18 must wear a helmet.
Yes, from a valid out-of-state license: pass the motorcycle knowledge test and pay the endorsement fee. Foreign motorcycle licenses don’t transfer; those riders take both tests. If the old endorsement expired 25 months or more ago, both tests are required.
Yes. Three-wheeled motorcycles need either a standard M endorsement or a three-wheel restricted endorsement; taking the skills test on a three-wheeler adds a three-wheel-only restriction. Idaho Motorcycle Rider’s Handbook p. 90
