Does Sixt require an IDP in Republic of the Congo?

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 are no widespread electronic tolls or vignettes; the upgraded Brazzaville-Pointe-Noire (RN1) corridor has some péage barriers paid in cash (CFA francs). Most travel cost is fuel rather than tolls.

Parking in Brazzaville and Pointe-Noire is mostly informal on-street with attendants who expect a small tip; there are no app-based or colour-zone systems. Use guarded hotel or business parking and avoid leaving the car unattended.

Police checkpoints are frequent and may seek on-the-spot cash payments from foreign drivers; ask for an official receipt and keep documents accessible. Common cited offences are missing papers, seatbelt and speeding violations.

Remain at the scene if safe, do not move vehicles when there are injuries, and summon police to file a report for insurance; exchange details with the other driver. If a crowd turns hostile, leave and report at the nearest police/gendarmerie post.
