Wildlife—typically deer—is one of the leading causes of crashes on Iowa roads. Knowing when deer move and how to react can keep a collision from turning deadly. And a parked car can turn deadly for anyone left inside on a warm day.

Know the rule

Watch for animals while driving, especially at sunrise and sunset.

Put it into practice

At dusk in November, a deer bounds onto the road with no time to stop. Brake and stay in your lane rather than swerving—then watch for others following it.

Check your understanding

Read the question, decide on an answer, then open it to check the explanation. These are Roadwise study questions based on the source handbook.

Which months does the manual identify as peak season for deer collisions in Iowa?
  1. January, February, and March
  2. June, July, and August
  3. October, November, and May
  4. September, October, and November

Handbook p. 57 ↗
You see a deer ahead and cannot stop in time. What does the manual recommend?
  1. Brake hard and swerve into the other lane
  2. Accelerate to pass the deer quickly
  3. Brake and turn the wheel at the same time
  4. Don't swerve; it causes a worse crash

Answer: Don't swerve; it causes a worse crash

The manual advises not to swerve, since it will likely result in a more severe crash.

Handbook p. 57 ↗
How hot can a closed vehicle's interior get in under 10 minutes, depending on conditions?
  1. Above 160°F
  2. Above 90°F
  3. Above 250°F
  4. Above 120°F

Answer: Above 160°F

The manual states the inside of a vehicle can soar above 160 degrees in under 10 minutes.

Handbook p. 59 ↗
If you spot one deer near the road, what should you expect?
  1. That deer is likely alone
  2. It will stay off the road
  3. More deer may be nearby; they travel in groups
  4. It will run from your headlights

Answer: More deer may be nearby; they travel in groups

Deer travel in groups, so always look for more animals if one is seen.

Handbook p. 57 ↗
Which heat statistic applies to a mild 78-degree day, versus the 160-degree figure?
  1. A parked car can reach 100 degrees within minutes
  2. A parked car can reach 160 degrees within minutes
  3. A parked car stays at outside temperature
  4. A parked car cools faster than outside air

Answer: A parked car can reach 100 degrees within minutes

On a mild 78-degree day, a parked car's interior can still reach 100 degrees in minutes; the 160-degree figure is for under 10 minutes in worse conditions.

Handbook p. 59 ↗
It is legal in Iowa to break a vehicle's window to rescue a person or animal trapped inside in the heat.
  1. True
  2. False

Answer: True

Iowa law allows breaking a vehicle window to provide medical attention to a trapped person or animal.
