3 questions from the Iowa practice test
1. How far from railroad tracks must a vehicle carrying placarded hazardous materials stop before crossing, unless an exception applies?
- At least 100 feet
- Exactly 5 feet
- Between 15 and 50 feet
- No stop is required when no train is visible
Show answer
Between 15 and 50 feet. A vehicle required to display hazardous-material placards must stop within the 15-to-50-foot range before crossing railroad tracks. The rule is a stopping distance range, not a five-foot or 100-foot requirement, and the absence of a visible train does not erase it. A police officer, highway traffic signal, or an EXEMPT sign can direct traffic to proceed without that stop. Check the vehicle's placard status and the crossing instructions before moving across.
2. How close to a railroad crossing is parking prohibited in Iowa?
- Within 20 feet
- Within 5 feet
- Within 10 feet
- Within 50 feet
Show answer
Within 50 feet. Iowa prohibits parking closer than 50 feet from a railroad crossing. The shorter distances in the choices are easy to confuse with other parking restrictions in the same section, including the five-foot fire-hydrant rule and the ten-foot stop-sign rule. Twenty feet is also used for a fire-station entrance, not the crossing. Separate the locations before recalling the number: railroad crossing means 50 feet. This buffer protects sight lines and leaves room around tracks for trains and responding traffic.
3. During extremely dusty conditions on a rural road, which lights should make the vehicle more visible?
- No lights until the dust clears
- High beams only
- Parking lights only
- Low-beam headlights
Show answer
Low-beam headlights. The manual directs drivers to use low-beam headlights during extremely dusty conditions so other road users can see the vehicle. High beams can worsen glare and are not the instruction given for this situation. Parking lights provide less useful visibility, and waiting for the dust to clear removes an important warning to approaching traffic. The light choice does not replace slower, alert driving. Reduce speed, expect limited sight distance, look for vehicles entering from the side, and keep enough space to stop if the dust hides a hazard.
