DC prohibits operating a vehicle whose windshield is cracked, scarred, clouded or otherwise defective so as to obstruct vision. Damage under three-quarters of an inch is permitted if it is not within three inches of another crack. Replacement runs roughly $300–$500 with a $250–$1,000 band, plus $150–$600 for recalibration.

Is it illegal to drive with a cracked windshield in the District of Columbia?
DC Municipal Regulations § 18-731.5 states that no motor vehicle shall be operated when the windshield is "cracked, scarred, clouded, or otherwise defective so as to obstruct vision." Cracks and chips under three-quarters of an inch are permitted, provided they are not within three inches of another crack.
DC is the only jurisdiction of the 51 whose written rule mirrors the federal floor exactly — the same three-quarter-inch limit and the same three-inch separation test. Everywhere else the federal rule sits beneath a different state figure; here they are one test, which makes the standard unusually easy to apply.
The regulation also bars any sign, poster or other non-transparent material on the windshield unless required by law, and requires wipers in good working order.

Does DC require an annual inspection?
No — DC does not require an annual safety inspection for privately owned vehicles. That removes the periodic checkpoint most of the inspection states have, but it does not remove the exposure: officers may stop a vehicle they believe is unsafe because of windshield damage.
DC and Arizona are the two jurisdictions in this research with no mandatory inspection, so in both the risk is a roadside stop rather than a failed test.

Does the District of Columbia waive the windshield deductible?
No. Only Florida, Kentucky and South Carolina require the deductible to be waived under comprehensive cover, and Massachusetts requires insurers to offer glass cover with a $0 or $100 deductible option. Arizona, Connecticut, Minnesota and New York permit a no-deductible add-on you must elect.
DC is in none of those groups, so whether you pay is set by your own policy. The more useful thing to confirm is recalibration, which most comprehensive policies fold into the glass claim rather than billing separately.

Can a chip be repaired instead in DC?
The repair thresholds are national rather than locally set. Chips up to about the size of a quarter and cracks up to roughly three inches are usually repairable; three to six inches depends on depth and position; past six inches usually means replacement.
DC’s three-inch separation rule is worth reading alongside that: two small chips close together breach the regulation even though each on its own would be both legal and repairable. Getting the first one filled promptly is what keeps you out of that situation.
How long before you can drive in DC?
Safe drive-away time is the point the bond can retain the glass in a crash and support airbag deployment — not full cure. Standard-cure urethane runs about 24 hours below 70°F, fast-cure about an hour, express as little as 30 minutes under controlled temperature.
An adhesive rated one hour at 70°F can need 8+ hours at 35°F, so ask what the figure is at the temperature they will be working in.
