Does Sixt require an IDP in Yemen?

Minimum age is region-specific: typically 21 in the US (18 in New York, where an under-25 fee still applies) and 18 in much of continental Europe such as Germany and France; drivers aged 21-24 pay a young-driver surcharge of roughly USD 25-30 per day in the US (about GBP 36 per rental in the UK, around EUR 5-6 per day in markets like Cyprus), and under-25s are usually limited to economy through full-size sedans, midsize SUVs and minivans.

A credit or debit card in the main driver's name must be presented at pickup; Sixt holds a security deposit of at least USD 200 plus the rental amount on the card, with substantially higher holds on premium/high-value vehicles, and debit-card acceptance and limits vary by branch and vehicle class.

A per-rental additional-driver fee applies; extra drivers can be added at any Sixt branch during the rental provided the main driver is present and the additional driver shows a valid licence (some European markets waive the fee for a spouse/partner). The driver must typically have held a full valid licence for at least 1 year (rising to 2-3 years in higher-risk markets such as Cyprus, while Germany requires the licence be held only since at least the day before pickup).

Most Sixt passenger vehicles may be driven across borders into listed neighbouring countries (e.g. France, Germany, Spain, Italy within Europe), but you must notify and get authorisation from the pickup branch in advance; a cross-border and/or one-way drop-off fee applies, and certain vehicle classes and destination countries are restricted.

Sixt does not require an International Driving Permit everywhere, but states that where local law requires it the IDP must be carried alongside the original home licence; if the licence is in a non-Roman alphabet (Arabic, Chinese, Japanese, Cyrillic, etc.) the renter must present an IDP or an official translation, and an official translation is also required if the issuing country is not party to the international driving-permit treaty.

There is no developed motorway or electronic toll network; long-distance routes instead pass through numerous military and tribal checkpoints where informal payments or document checks, rather than formal tolls, are the norm. Carry cash and copies of your IDP, passport and any travel permits at every checkpoint.

There are no organised paid parking zones or apps; in Sana'a and Aden you simply park on the street, ideally in a guarded hotel compound or where an attendant watches the car for a tip. Vehicle theft and carjacking are real risks, so never leave a car unattended in an unsecured spot.

Formal traffic-fine enforcement is weak and inconsistent amid the conflict; the bigger risks are detention or fines at checkpoints for missing permits, and a strict nationwide alcohol ban means any drink-driving is treated severely. Do not photograph checkpoints, police or military.

Stop and do not move the vehicles; there is no reliable single emergency line nationwide, so contact local police or the nearest checkpoint/military post, which often handle incidents. Obtain whatever written report you can for insurance, and be aware that injury crashes can trigger tribal blood-money (diya) claims that are settled locally.
