A 2-minute lesson from the Missouri course. Read the rules and examples, follow the handbook page references, and check your understanding before you move on.
You take a vision test with every new or renewal license or permit. It checks sharpness (acuity) and side (peripheral) vision. If you wear glasses or contact lenses, you may need them for the test.
Your peripheral vision measures 60 degrees in each eye, which meets the 55-degree standard. A person with sight in only one eye passes if that eye reads at least 85 degrees.
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.
What is the standard minimum visual acuity required to pass the Missouri vision test?
20/20 in both eyes
20/70 in one eye
20/100 corrected
20/40 with either or both eyes
Answer: 20/40 with either or both eyes
The standard minimum acuity is at least 20/40 with either or both eyes.
If your natural and corrected vision are both worse than 20/160, what happens?
You can't take the driving test or be licensed
You get a daylight-only restricted license
You must wear corrective lenses to drive
You may drive only within a 25-mile radius
Answer: You can't take the driving test or be licensed
If both natural and corrected acuity are worse than 20/160 (or peripheral vision is worse than 70 degrees combined), you cannot take the driving test or hold a license.
If your peripheral vision is worse than 70 degrees combined even with correction, you may still take the driving test as long as your acuity is 20/40 or better.
True
False
Answer: False
If your peripheral combined vision is worse than 70 degrees (or acuity worse than 20/160 both natural and corrected), you cannot take the driving test regardless of the other measurement.
